When a switch stops switching then it s time to troubleshoot and repair or replace the switch. Turn off the power to the switch at the main circuit breaker or fuse panel. Remember that white wires may not always be a neutral wire especially if you see a white wire that is connected to a light switch. Electrical boxes must be flush to the wall surface if the wall surface is a combustible material.

A wire getting loose in a terminal screw or in a wire connector at the switch or light fixture could cause the flicker. Use a voltage tester to verify the circuit wiring configurations. Even if this happens only occasionally it s still time to replace the switch. Until you get the time to do it though you might have to flip off the breaker to avoid wasting energy.
