The switch I bought for my shower had the wires for the neon light hard wired in by the manufacturer, with the light staying permenantly on. I took it back to where i bought it from and had it changed . The new switch did exactly the same, ( light stayed on ) I had to cut the wires and rewire it myself to the output side. Made sure the circuit breaker was OFF first. I wonder if this was part of a bad batch of switches.
