A time switch, also known as a digital timer or an electronic timer, is a device that controls an electric switch. The time switch is an electronic device that controls the 'on' and 'off' timing of electrical equipment. Each of these buttons has its own indicator light. Once you’ve selected one of the preset countdown settings, the indicator light will flash for the last 10 seconds of the chosen time. This lets the homeowner know that the bathroom exhaust fan is about to shut down. On top of that, the LED indicator lights usually provide a bit of illumination, making it easy to choose the desired setting even in pitch darkness. Fired when a timer has completed and includes finished_at date/time in event data. finished_at should usually be now, or within the last several seconds, but if the restore property is true, finished_at may be further in the past since this event will fire on startup for any timers that would have ended while Home Assistant was stopped. Plug-in time switches are available as a digital timer, meaning they often feature a memory that allows the time to be set for a specific time during a 24-hour period, or for multiple times to be set. Mechanical timers, on the other hand, represent a specific period such as 15-minute intervals. Lighting Timers

Timers for both internal and external lights known as a lighting timer are ideal when used for home safety or business safety purposes as a deterrent to potential opportunists or burglars. You can programme your timer to switch the lights 'on' and 'off' at a certain hour of the day, giving you complete control and making it look as if you are at home or in the building. Is there an override switch, i.e. if I set it to switch off after 2 hours and then decide I need to have lights on for another hour will I need to open the box to do that ?I want to use this unit to switch four LED driveway lights, total combined load is about 8W, but have heard that some units don`t work with such low loads. Do you think that it will work okay in this application?

Will this timer function correctly in a pigeon loft with no mains. In a scenario where lights are 12volts leds and power to unit is from 12 volt battery(s) Light on is adjustable from 1 to 8 hours. Can also be set to operate from dusk till dawn if required. There are also modes for turning things on or off on specific days, multiple days of the week or your own chosen pattern. What I really like about this plug-in timer is the random mode though. If you’re off on holiday, simply plug in a light and it will turn on and off randomly to confuse any would-be burglars. All of this is controlled via a single button, which is situated right below the countdown time options. This kind of one-touch convenience is always a big plus in my book. Press the ‘Program’ button, then use the ‘Week’, ‘Hour’ or ‘Min’ buttons to select the days, hours and minutes you would like your timer to stay on for, as well as the time you’d like it to switch on. Then plug your device into the timer. Do timer plugs use a lot of electricity?
