How A Light Switch Works
Electricity is constantly flowing through the wiring in your home. It only stops when it comes to a switch that is in the off position. The switch has two terminals that allow electricity to pass through when it is in the on position. But it stops the flow of electricity when the switch is in the off or open position.
Why Does My Switch Crackle When Turned On?
When electricity flows, it creates heat. But that heat is contained safely by the insulation on the electrical wiring in your home. If electricity somehow escapes the wiring and insulation, it begins to build up heat and creates the potential for a severe electrical fire. As the electricity increases, it starts to arc and attempts to jump the gaps.
