Hello all, my first post:
I am considering installing an air actuated switch within a shower enclosure to control a recessed light above the shower. I am surprised that I cannot find information online specific to doing this. Everything I read is in regard to garbage disposals or pump actuation in a whirlpool. My question is would it be legal to install an air transmitter button in the shower wall within easy reach if I made sure to locate the switch box higher than the pushbutton transmitter to ensure any leaks through the wall did not find their way along the air tubing inside the wall into the switch box?
