Lighting has long become not just a source of light, but an integral part of the home interior, which favorably emphasizes the advantages of the room and competently hides its shortcomings. It helps to create a mood. Since evening TV viewing is carried out with dim lighting, and conversations with friends take place in a room full of light.
Timer switches for forgetful users
Lighting control refers to the "smart home" system, which is quite widespread in many civilized countries. She, as a rule, is tuned to certain situations and accordingly responds to them. Maintaining the microclimate at the proper level, monitoring the operating mode of electrical appliances and engineering systems, starting up, monitoring the operation and turning off various household appliances in order to save resources and ensure safety - this is not a complete list of functions included in the Smart Home system. One of the elements that enter this system through lighting control is a light switch with a sleep timer.
Classification
To control, adjust and control the lighting, light switches of different designs are used, which differ from each other in capabilities and degrees of protection. According to the type of current opening device, they distinguish:
- Pushbutton switches, which, when pressed, alternately open or connect the contacts.
- Rotary switches equipped with a rotating contact mechanism. When the position of the rotary switch changes, the contacts close / open.
- Rocker switches, inside which there are 3 pairs of contacts and a plate. Such models do not break the circuit, and the plate is thrown to the other 2 contacts, i.e. It is not a shutdown, but a switching.
Modifications of Timer Switches
Switches with a trip timer can be of the following modifications:
- Watchdog Timer.
- Timers designed for exhaust ventilation in bathrooms.
- Switches with a timer to turn off the light.
Depending on the principle of operation, timers are mechanical and electronic. In the first case, the necessary work cycles are set when turning a special disk. In electronic versions, all parameters are set by pressing certain buttons on the control panel.
Watchdog Timer
This device is indispensable for homeowners (suburban homes, cottages or apartments), which for a long period of time remains unattended. Such timers imitate the presence of owners in an empty home, turning on and off the lighting in an economical mode (the so-called ghost mode). Of course, such a timer will not be able to completely insure against the intrusion of uninvited guests, however, petty thieves will be scared away for sure.
Lighting switch with motion sensor
This is a great way to rationally organize street lighting or in non-residential premises and on stairs. The light is turned on by a signal from a motion sensor that is built into the circuit. Turning off the lighting is done after turning on after 5 minutes also automatically.
Push button switch with timer
The light turns on by pressing a button and turns off automatically after a specified period of time. To turn on the lighting again, press the button again.
Timer manufacturers produce analogue electromechanical models of weekly and daily switches for lighting, ventilation and other devices. The minimum time set on such devices is 15 minutes for the daily switch and 2 hours for the weekly timer.
For annual programs use modular electronic timers that use software keys.
Switches with a light-off timer are convenient in hallways, basements, garages, and toilets. This is ideal for places through which you have to go with busy hands, where the light will automatically turn on when you enter and turn off after the user leaves.
Switch with shutdown timer for ventilation
Switches are also used for the rational use of exhaust fans installed in bathrooms and kitchens. Depending on the program used, they can turn off the fan after a certain amount of time after starting work, as well as turn it on and off several times during the day. This helps to maintain a certain level of humidity in the room, and without excessive consumption of electricity.
Legrand Products
In search of high-quality, reliable and beautiful wiring equipment, consumers increasingly pay attention to sockets and switches from the famous French company Legrand. The products meet the highest European quality standards.
The automatic switch with the Legrand shutdown timer allows you to automate the inclusion of lighting.
