About the MyDome Light Switch Timer

The Light Switch Timer - The easiest way to realistically light your home during the evenings whether you are out with friends, away on holiday, working late or just want to come home to a welcoming light. Helping you keep your home safe.

Easy DIY installation in 1 minute

Absolutely no wiring is required at all

Works on any type of light bulb

Can be used to control 1, 2 or 3 gang switches

Long battery life - Upto 2 years of daily use

Never Leave your home in the dark again.

The Light Switch Timer simply fits over any standard 1,2 or 3 gang light Switch allowing you to programme your main lights to turn On and Off multiple times a day.

There is no wiring involved and you do not need to change your existing switch. The timer simply sits over your light switch and takes less than a minute to install. There is a 30 second video at the bottom of the page.

It's always nice to come home to a welcoming light on in the house and nobody wants to come home after a fantastic holiday or a great night out to find their home has been broken into.

You can still operates the lights when you are home using the on and off buttons meaning you can leave the unit in place all winter and never have to worry about your lights when you get back after dark.

Added Security

The Light Switch Timer is approved & recommended by The Police through their Secured by Design crime prevention initiative – in recognition of its effectiveness and ability to reduce the risk of burglary.

Burglars often use the tell tale sign of a lamp on a timer as a sign that you may be out or on holiday. The Light Switch Timer is more realistic as it uses the main lights in your home. It can also be used for external security lighting, or on the porch as a welcoming light when you get.

Programs and Usage Explained

The 24-Hour, 7-Day Digital Timer enables you to program your lights to switch on/off at specified times, over individual days or across a combination of days.

You can set up to 9 different program combinations allowing you to recreate usual activity in the home whilst you’re away.

A random feature – which will turn the lights on and off for a short period at random times during the early hours of the morning.

The unit can be installed on switches with one, two or three switches (gangs as they are called). It even allows you to select which of the switches you want to operate on the timer by simply installing or removing the control wheels at the rear of the unit.

Reducing your energy bills

Programming your lights to only come on when required can also save you money. Not leaving lights on when not required will help the environment too.

Remember burglars don't have day jobs - Leaving a visible light on during the day alerts that you are out and won’t be back till late.

Leaving your lights on during the winter months and running just one 100 watt bulb for 7 hours a day with electricity prices at 11p per kWh would cost over £14 pounds. And produce over 50KG of CO2 Emissions in one year!

  • Q: Will it work with my light switch?

    A: The Light Switch Timer has been tested on all “standard” light switches.

    If your light switch is similar to ones below then you will be able to control them with our Light Switch Timer.

    Compatible with single, double and triple standard switches

    The Light Switch Timer is not compatible with:

    • Large Brass switches Ornamental switches larger then 9cm across
    • Flat plat or low profile switches
    • Dimmer switches

    The Dimensions are Height 130mm * Width 95mm * Depth 53mm

  • Q: Can I choose which switches the unit controls?

    A: Yes on double or triple gang switches you can place either one or two or three control wheels on the switches you want to operate. So you can choose to only operate one switch on a three gang switch.

  • Q: Do I need to know about wiring to install the Light Switch Timer?

    A: You will not be accessing or exposing any wiring during the installation process – it is however, always a good precaution before attempting any installation to turn off the electricity supply at the main fuse box during installation of the cradle.

  • Q: I'm going on holiday for 3 weeks – can I use the Light Switch Timer?

    A: First check the wheels go up & down when the on off button is pressed.

    Ensure the wheel is installed in the correct slot for the switch you want to operate.

    After you have checked the above you may need to install the small the “n” shaped plastic insert into the cradle before reinstalling.

    The unit should now successfully operate your switch.

    Should you still have trouble just get in touch.

Customer Reviews

Great little machine this. Easy to program, many program options and easy to fit (no wiring to mess with). Enables you to time light switches to come on and go off.

Such a great product. So easy to install and use. We use it daily, had mine installed for the past 6 months and it has worked flawlessly.

Reviewed on Amazon

This timer is easy to fit and reasonably easy to program. The instructions are written in good English (not a foreign translation) and take you step by step through the programming sequence.

    Mr. P. Smith

    I’ve had this product in use for almost a year. It is incredibly easy to fit and use, and easy to programme (compared to most other timers I’ve tried). The fact that you can simply lift it out of the cradle at any time and use the switches normally makes it ideal for anyone who’s tried to use a built-in electronic timer manually. Whoever designed it deserves recognition; a very original answer to a decades-old problem, and one I have no hesitation in recommending unreservedly.

    Mostly this is a good little unit, particularly helped by avoiding any involvement with wiring.
    First fit – nothing happened. Added both packers – still nothing happened. I then had to buy a new lightswitch. The original (Tenby) switch must have been low-profile at 7mm thickness. I got a new switch at B&Q at ~9mm overall thickness and this worked, after adding one of the packers.
    The application was to provide some random evening operation of a kitchen light in an empty property. I was disappointed that the Random function could not cater for this as it is programmed just for a varying 3 minutes at different times each night between 1am and 5am, meant to simulate loo trips for a bathroom. As the unit has 9 programmes, I was able to get round this by programming varying kettle trips each evening on top of fixed meal preparation and bed time drink.
    The unit is electro-mechanical with a wheel running down / up the switch to activate it. Hopefully it should be durable.
    Overall it seems to be a well thought through design with on / off override buttons. Could have been better with a sustained hold on hours / minutes button to advance rather than a push per increment.
    If the property is occasionally empty then the unit is easy to install into the cradle sitting on the switch. When you return all you need do is remove the switch from the cradle to go back to easy access to the basic lightswitch.

    Easy to fit and use requiring just a screwdriver to adjust light switch screws. The timer switch fits on top of normal rocker switch.

      Do I need a doctorate in electrical engineering or have I missed something here? We are away for long periods with a lifetime on cruises so it isn’t easy to get home to find its gone off by accident or someone has broken into. Please enlighten me in words on 2 syllables or less. My brain shuts down my eyes show ‘Tilt’ and I shake violently when I get computer info from the ‘greys’ and I have to laydown and recover in which time I have forgotten what the greys have said.

    Have a few of these switches, excellent and easy to install. Only drawback is noise of switch going on and off if the switch is in room where you are, otherwise you don’t hear it. Fully recommend – unfortunately have not been able to locate a supplier in Dublin anymore.

    W Kimble

    We have 2 outside lights a nice porch light and a garage flood light. It always seemed a waste to have them both on at the same time. So I have this setup so that the floodlight comes on at midnight for security when the other one goes off. It has been working a treat for a number of weeks now with no issues and took seconds to setup.

    This is a fantastic gadget which is very easy to use. It works on a normal light switch and turns the switch on and off according to preset times by means of a small wheel/cog powered by standard AA batteries. It allows you to time a main light to turn on and off when you are out avoiding the need to plug in a lamp. A much better idea, especially if you have pets that could knock a lamp over. You can easily override the timer by pushing an on/off switch on the unit. It is installed simply by slipping a plastic cradle over a light switch and the placing the timer unit in the cradle with the cog wheel lined up with the switch. The unit can stay in place continuously or be removed if desired. It does make a whirring noise turning the switch on and off but it is only a second or so of noise. There are 9 separate programme opportunities over 7 days allowing almost any combinations of timings on different days. There is also a random function which turns the light on in the night at random times for about 3 minutes each time. This is useful if you are away as it mimics someone getting up in the middle of the night for a comfort break. I would suggest not using this feature if you are at home otherwise the noise might disturb you. The unit can be adjusted to move 1, 2 or 3 cogs at the same time depending on how many rocker switches are on the light control.

    I ordered this because I wanted a product that was able to cope with LED bulbs and the electronic replacement light switches you can get won’t work with low wattage LED bulbs One small point to note is that it does project beyond the original light switch about 30mm. Brilliant idea which works well – highly recommended.

    Works really well though I find I have to look at the instructions each time I want to programme it well. Had a small issue when it wouldn’t flick the switch but by using the enclosed packers it was a doddle to adjust the light switch relative to the timer – hey presto! worked brilliantly.

    Very simple, but fully functional. Programming very flexible. A well thought out and good quality product. I will probably buy another one to cover other areas of the house. Just make sure your light switches are compatible.

    Delighted with this buy! Used it on a standard 3 switch panel. Very easy to fit. Had to unscrew the screws but is extremely easy. Only slightly noisy when turning on/off, otherwise silent. Display is nice showing day, time and temp. Can manually turn on/off with buttons on display. The only draw back is all light switches either turn on/off, you can’t work them independently of each other.

    Easy to set up, although at first I got it to switch the lights on but not off, so I adjusted the cogs into a different position than the instructions & added the part that makes it sit out a little ( you’ll know what I’m on about if you buy one!) it worked perfectly. I’ve posted some photos to show the item.. I initially thought it was a bit bulky and intended to take it off & just use it while away on holidays or in the winter to turn on garden lights but I’ve got used to it and have left it as it looks like a heating control panel. I am so impressed that I ordered another for our porch & one for our under cupboard kitchen lights which is a 3 switch, (only need it to switch on 1) There’s multiple time settings, and you can manually switch on/off. I thought the price about right even if it is just made from plastic, it would be extremely costly to have our light switches replaced to do the same job, I can’t see the point of having a temperature gauge though. It is a little noisy ‘whirring’ when switching on & off, but that’s hardly what I call a problem. i have used them on 1 switch, 2 switch and 3 switch plates. One review said they had to buy batteries but all of my 3 orders came with batteries. Company is excellent to deal with.

    What a clever little device. I needed a timer for the hall lights but my old one would not work as I had new LED bulbs. So, I saw this one which uses a motor to switch on a simple on/off switch. I had to remove the old timer and replace it with a a normal switch but assuming you already have one in situ, there is no wiring to be done. Simply loosen the screws and slip the cradle under the edges and tighten up the screws again. Now, pop 2 batteries (not supplied) into the unit, adjust the wheels for either a 1, 2 or 3 switch gang, programme the unit and slide into the cradle. Tested by hitting the on button, turned the light on accompanied by a loud whirring sound from the device as the wheel hit the old rocker switch. Obviously, the same happens when switching off. That noise might wake someone up if the switch is in or near a bedroom. It would certainly scare a burglar if they had entered the house!

    But, one word of warning, if you are using this in conjunction with a configuration that allows eg a hall light to be switched on and off upstairs and downstairs, it will confuse the unit if you do either from the other switch. So, you need to ignore the other switch (unless there is an emergency and you need light immediately). I will get round this by setting the off time late on after I have gone to bed (I used to switch the downstairs light off from the switch at the top of the stairs).

    Hope this all makes sense and I would recommend this device especially if you intend to use LED bulbs.
