AS Photo Sensor Switch

AS photo sensor switch consists of a sealed CDS photocell and a Snap-action bimetallic relay. The unit automatically turns on or off the lighting according to the light intensity changes.

  • Electric light control switch
  • CDS photocell
  • Suitable for street lighting, factories, gardens, ports, airports, farms, parks, any other place which needs to automatically control the lighting.
  • Automatically turn on or off the load circuit according to changes in light intensity.
  • Delay function can resist interference according to the short-term ambient light intensity changes.
