Nothing noticeable changes when it’s on or off and it’s not near a particular electrical outlet.

  1. Is it by chance located somewhere near a bathroom? Looks like a boiler/water heater switch.

  2. If it’s inside or near the bathroom door, then it’s supposed to be for the electric water heater/boiler. The built in light indicates that the water boiler is active and heating water for use.
