A slide switch is a type of electromechanical switch that opens or closes an electrical circuit by sliding a small lever or actuator back and forth. It allows the user to control the flow of electricity in a circuit in a simple and reliable way.

Slide switches typically have two or more positions, such as ON/OFF or multiple settings, and are commonly used in low-voltage electronic devices. Inside, a metal contact moves along a set of fixed contacts as the lever slides, completing or breaking the circuit.

They are widely used in electronic gadgets, toys, remote controls, and small appliances where compact, easy-to-use switches are needed. In simple terms, a slide switch is a small switch that lets you turn a circuit on, off, or switch between settings by sliding a lever along a track.
