What is on on off switch?

An on-off switch is a type of switch that controls the flow of electric current in a circuit. This switch can be in the form of a physical toggle switch, rocker switch, or push-button switch, and it has two states: on or off.

When the switch is in the off position, the circuit is broken, and no electrical current can flow through it. Conversely, when the switch is in the on position, the circuit is complete, and electric current can flow through it.

On-off switches are commonly used in electronic devices, household appliances, and industrial machinery to provide a convenient way to turn them on or off. They usually have a rating indicating the maximum amount of current and voltage that they can handle safely, and they may also have additional features such as a pilot light to indicate the switch position or a safety cover to prevent accidental activation.
