250V Silver Contact Self-Resetting Limit Switch

The travel switch (also known as a limit switch) is an automatic control component triggered by mechanical motion. Its core function is to detect the displacement or stroke of an object to achieve the opening and closing of circuits, the start and stop of equipment, or limit protection. It is an indispensable 'safety sentinel' and 'action commander' in industrial automation and electromechanical equipment.

The door cover edge of the drum washing machine is equipped with a limit switch, which only connects the circuit when the door cover is completely closed and fastened. The washing machine can only start the washing process under these conditions. If the user opens the door cover during the washing process, the switch immediately disconnects the power to the motor and the water inlet valve, preventing the drum from continuing to rotate and causing clothes to be ejected or water leakage, while also pausing the water intake to ensure user safety.
