Mell What is the safety device for television?
TVs, audio, and computer equipment have circuit breakers that protect their sensitive electronic circuits. For added protection from lightning and power surges, you can plug them into a surge protector. Another example of a safety device is the tip-over switches that shut space heaters off if someone knocks them over.
