Not enough to activate the load just enough for the light in the switch to work. With the switch off it still had current at the sockets. One possibility is that the switch is wired on the neutral side and there is a ground fault between the switch and the outlet. As i stated i changed the switch but the light stays on constantly even without being connected to the switch as long as the breaker is onthe box has three set of wires blackwhiteground from the fixture a blackwhiteground and a blackredwhiteground.
If that does not work then you may have lost a connection with the neutral wire of the circuit. Thanks for your electrical question jim. Light fixture still hot with switch off 595231 0227. The switch does not work. A lighted switch has the light across the contacts. About 40 volts on the.
