This light Switch can be mounted on a standard sized switch board to control a light automatically. It can be used as an automatic light switch as staircase, balcony or toilet and thus can be useful in saving electricity a lot.
On top of the device, there's a 3 position switch-
- position 1 - ON : Connected light will be always on. Just like a manual switch - position 2 - OFF : Connected light will be always off. Just like a manual switch - position 3 - Auto/PIR: Connected light will turn on automatically when a person comes in front of the switch within 10 meters. Then after a while, it'll turn off automatically.
Also, there're 2 knobs inside the device that the user can rotate to adjust 2 things -
- Time delay: Control how long the light remains ON before turning OFF in PIR/Auto mode. - Light sensitivity: Make the switch work only at night in PIR/Auto mode.
