I have a switch that used to control outdoor lighting. It no longer does any more and I'd like to just leave it off permanently. Is there an easy way I can terminate it from within the gang box? Eventually I might want to use it again so I don't want to completely rip out out the wiring/circuit; just leave it off and replace the switch with a faceplate cover.
Turn off the power at the panel for this circuit (flip the circuit breaker).
Remove the cover plate from the switch.
Test with a non-contact tester to make sure that there is no power in the circuit box.
Unscrew the switch.
Remove the two wires from the switch (unscrew or, if they are press in types, cut them close to the switch)
Straighten the wires and screw a wire nut over the bare end of each wire.
Wrap electrical tape over the nuts and the wires.
Carefully bend them back into the box.
Put a blank cover over the box.
