automatic light switch

It seems that the lights in the restrooms/shower house are always being left on when guests leave. Signs are posted to remember to turn off the lights when leaving, but for whatever reason the lights are often left on, sometimes overnight. An easy way to keep this from happening is to install a motion activated light switch, or “occupancy sensor” as the manufacturer calls it. I decided to pick one up to install and try out first before replacing all of the switches. The switch has been installed for a total of 30 minutes, but so far it seems to be functioning properly. The switch turns on when someone enters the restroom, and stays on as long as there is movement. The time before the lights turn off is adjustable. I set ours for 15 minutes; hopefully, this will be long enough as I don’t want the lights to go off on anyone in the shower. We will see, and will install another in the second bathroom if this one seems to work ok. The switch can still be turned on and off manually. The Leviton PR150 switch was about $20.

The old switch that was getting left on, also was brown and sort of ugly.

Installing the new motion sensing light switch.

The new occupancy sensor looks a lot better than the old switch and should save a decent amount of electricity.
