An electromechanical switch is a device that uses a physical mechanism to open or close an electrical circuit. Unlike purely electronic switches, it relies on moving parts—such as levers, buttons, or springs—to make or break a connection, allowing current to flow or stopping it.

Electromechanical switches come in many forms, including toggle switches, push-button switches, rocker switches, and relays. They are commonly used to turn devices on and off, select modes, or control circuits in a wide range of applications.

These switches are found in household appliances, industrial machinery, vehicles, and electronic equipment. They are valued for their simplicity, reliability, and tactile feedback, which lets users feel when the switch has been activated.

In simple terms, an electromechanical switch is a manually or mechanically operated device that controls the flow of electricity by physically connecting or disconnecting a circuit.
