The efficient owners know that allowing lighting to work without unnecessary needs at today's electricity prices is an unacceptable luxury. Even a regular light bulb, which is left on for a long time, can cause a rather impressive gap in the budget . This is why the switches with the disconnection timer, which automatically turn off the electric power after a certain time after switching on, are becoming increasingly important.
Light switch with timer
Speaking of automatic light switches with a trip timer, we can distinguish several of their main varieties:
- Timer-watchman - an indispensable device for owners of summer cottages, suburban houses or apartments, whose dwellings for long periods remain unattended. Such timers through arbitrary periods turn on and off lighting in economy mode (spooky mode), thus creating the illusion of the presence of a person there. Of course, such a timer can not insure completely from the intrusion of uninvited guests, but petty thieves will surely scare them off.
- A light switch with a motion sensor is an excellent way to rationally organize street lighting or lighting on stairs or in non-residential premises. The light is switched on by means of such a switch on the basis of a signal from the motion sensor integrated in the circuit. Five minutes after turning on the light is also automatically turned off.
- Pushbutton light switch with trip timer - in this case the light is switched on by pressing the button and is switched off automatically after a preset time. To switch on again, press the power button again.
By the principle of operation, the timers can be either mechanical or electronic. In the first case, the necessary work cycles are set by turning a special disk. In electronic timers, all parameters are set by
Switch with trip timer for ventilation
Another task for which switches with a sleep timer are used is the rational use of exhaust fans installed in ventilation in kitchens or in bathrooms. Depending on the program, such switches can either just turn off the fan after a while after starting work, or turn it on / off several times a day at certain intervals. This helps maintain a certain level of humidity in the room, while avoiding over-expenditure of electricity.
