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.
Why does my light switch make a noise?
Light switches get much use in most households. And over time, the inside of the switch begins to wear out. At this point, the switch is not making solid contact with both terminals when it is in the on position. That can result in the power flowing intermittently and lights flickering. It can also be the reason that you hear crackling, popping, or hissing sounds as the electric current arc inside the switch. And what the sound is telling you is that it is time to replace the switch before there is serious damage to your home or you suffer a severe electrical shock.
How does electricity flow through a switch?
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. When you turn off a light, you are just creating an opening that stops the flow of electricity to the light. To turn the light back on, you flip the switch to complete the circuit and allow the electricity to flow to the light.

How Does a Standard Light Switch Work?
Electricity powers lights and other devices through a continual flow of current. A light switch has two terminals. When the toggle is in the “on” position, the power supply wire (black wire) connects the two terminals, allowing electricity to flow through to the light. Turning the light off is simply a matter of interrupting the flow. When the switch toggle is flipped to the “off” position, it opens the connection between the terminals, stopping the flow.
