What causes a light switch to stop working but light stays on?

A light can stay on when the switch is off if the switch contacts are stuck closed, the wiring bypasses the switch, or a 3-way/smart switch is miswired. In many Mountainside, NJ homes, we also find backstabbed connections that fused, or a failed smart-switch relay keeping the load energized. Our licensed electricians diagnose and correct these safely and fast. Quick checks: - Turn off the breaker and verify power is off with a tester. - Do not work on live circuits. - Call a licensed electrician (Electrical License: 34EB00790200).
