Switches are heavily used in daily life and can wear out or malfunction over time. Not all faults require a complete switch replacement. Here are four common causes of electrical switch failures and their solutions.
1. Loose Wiring
Cause: Vibrations from frequent switching can loosen the wires if not connected tightly.
Solution: Reconnect the wires securely to fix the issue.
Cause: Using a switch with an incorrect amperage for high-power appliances can lead to a blown fuse.
Solution: Replace the switch or, if possible, just the fuse with the correct amperage.
3. Melted Live Wire
Cause: High-power appliances can cause the live wire to melt over time.
Solution: Reconnect the live wire inside the switch to resolve the problem.
