Energy Saving Auto-Switch LC-753


LC-753 is a state-of-the-art single wall switch box mountable energy saving auto-switch for automatic lighting control of commercial or residential applications.

It can be used to switch the light or other loads on and off by sensing the movements within detection range. Adjustable LUX and TIME controls allow user to set the switch operation timing according to the ambient light level and light-on delay time as desired. Audible delay-end warning can be enabled to indicate the approach of delay time end.
