Light switches and electrical wall outlets might become damaged at any time, operating intermittently or not at all. It can also be dangerous, in addition to making the light or appliance unreliable.

If your light switch makes any sounds, you should replace it immediately to avoid an electrical fire. Switches with loose connections will overheat and arc, producing charring at the connection sites.

Hence, when you’re dealing with complicated wiring, broken light switches, or possible fire dangers, the best thing you can do is call in a pro.
