  • How reed switches work magnetically operated switches

    Nov 27 2021  A switch is like a drawbridge in an electric circuit. When the switch is closed the bridge is down and electric current can flow around the circuit when the switch opens the bridge is up and no current flows. So the purpose of a switch is to activate or deactivate a circuit at a time of our choosing.
