WebAug 25, 2024 · Circuit breakers have a top and a bottom so that electricity flows through them correctly. When too much current runs through a circuit breaker, either the metal strip bends and flips the switch, or the magnet becomes strong enough to pull a metal lever that flips the switch. When that switch flips, it interrupts the circuit. how to remove cached dataWebThe electric circuit is completed by installing a push switch which you can press to generate sound in an electric bell.
