The dangers of not replacing
Occasionally the surrounding plate will crack and then possibly begin to fall away from the wall. Other times the crack can form on the plastic clips on the edges of the switch mechanism.
When these clips break the plastic cover can very easily fall out and live 240V contacts will become exposed.
Whether the plate has fallen away from the wall or the rocker switch plastic is broken, both situations can lead to direct contact with live electricity.
It is advisable to install safety switches to protect against electrocution if by chance a person comes into contact with these live parts. A functional safety switch will trip before a dangerous situation can occur if it detects earth leakage such as a person grounding a live terminal. Safety switches are an important part of an electrical installation, should not be overlooked and are now mandatory on all electrical sub circuits in new installations or when modifications occur to existing electrical systems.
How to identify switch faults
- Inconsistent power
The switch is not consistently turning on the connected device or light fixture
- Flickering lights
If the lights connected to the switch flicker or dim unexpectedly it could indicate a problem with the switch
- Warmth or Burning smell
A faulty switch might feel warm to touch or you may notice a burning smell around the switch
- Visible damage
Physical damage to the switch such as cracks or discolouration can indicate a fault
- Noisy operation
Unusual sounds like buzzing or crackling when operating can indicate a fault
- Tripped circuit breaker
If the switch frequently causes the circuit breaker to trip there may be a fault with the switch or the wiring
