I am replacing a bad 10+ years old photo sensor light switch. The bad sensor' plastic has gotten dark and opaque.

This is photo sensor is for a commercial contactor switch which operates at 277 volts.

I am replacing with a brand new Intermatic K123C photo sensor control (277 volts). If you are replacing a 120 volts system, use the Intermatic K121C. I bought mine from Amazon, if you are looking to buy them, I would appreciate you to click on my link to support my youtube channel. :-)

Here are 2 links to buy Intermatic Photo Sensors:

208 - 277 volts:
127 volts:
