Why are light switches yellow?

Most plastic electric switch covers are treated with bromine, a flame retardant. When exposed to ultraviolet rays, bromine turns yellow, making your switches look old and worn out. It cannot be cleaned with regular light cleaner or household sprays, but you can clean it using baking soda and bleach.

Can a light switch fail?
Like any other thing in the world, they break down over time. Every light switch, at some point, will go bad. But they're a simple device that doesn't have a lot of moving parts so they're built to last and don't break down often.

Why do light switches crackle?
Either the wire insulation is worn, or the lines get loose. The copper wiring is exposed to the air, and when electricity flows, it escapes through these gaps or holes, causing heat to accumulate. These crackling or popping sounds indicate the currents arcing inside the circuit.

What color light switch covers?
Most switches and outlets are white with white wall plate covers—but not all of them. Some light switches and outlets can be gray, black, almond, or ivory (to name a few). This isn't a big deal when they already have matching wall plate covers on them.
