There can be several reasons behind your light switch sparking when turned on. But it isn’t necessary that it is always a bad sign. Sometimes, it can also be normal to experience a small spark. So when you turn on a light switch, you may see a small spark, which occurs due to the electricity attempting to leap from one contact to another. This is called a load arc. But if you notice large and or frequent sparking, there may be a problem.
Reasons why Your Light Switch is Sparking
Sparking can happen due to loose wiring. Check the wiring by first turning off the breaker and then removing the cover.
See if you notice snapping sounds, scorch marks or visible signs of smoking, combined with sparking, this can be an indication that your light switch has a fault.
Another reason for sparking can be that the light switch has worn out, which happens when the switch has reached the end of its life.
In such a case, I would suggest you contact a licensed electrician and get the replacement done for your light switch.
