You don't have to take the switch apart or expose the cables in order to test a light switch. So, how to test a light switch without removing it? You can determine whether the switch is functioning or not, whether power is reaching it, or whether the problem is elsewhere in the circuit by using simple instruments like a multimeter or a non-contact voltage tester.
How to Test if a Light Switch is Working?
Hold the non-contact voltage tester close to the faceplate or the switch terminals. The switch is getting electricity if the tester beeps or lights up when the switch is on.
Multimeter Test (Voltage Mode): Set an AC voltage on a digital multimeter. Don't take the probes off the wall; instead, carefully place them on the switch terminals. A reading shows that electricity is present.
Turn on the switch and watch the connected light to perform a bulb test. If the switch indicates voltage but the bulb is not lighting up, the problem might not be with the switch but rather with the wiring.
These methods can help you test a light switch without removing it.
