Can a light switch cause a fire?

Overloaded Circuits

The main reason a light switch feels hot or shows signs of heat damage is from circuit overload. This happens when too much current flows through the switch. If the light switch is rated for 600 watts but 1,000 watts is flowing through it, the switch will get hot and possibly lead to a fire.
