If you can be alerted to the need for a replacement or repair early on, you may be able to correct the problem before it becomes disruptive or inconvenient. Being proactive about your light switch can also ensure that you're safe from electrocution and fires that occur when faulty wiring is neglected.
A few warning signs to look out for:
- You smell an electrical burn of any kind around the light switch
- You hear strange zapping or popping noises when you turn the light on
- The lights begin to flicker
- You're given a shock when you touch the switch
- Appliances aren't working correctly
- There are visible signs on blackening around the edges of the plate
