Independent Dual-Pole Limit Travel 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.

Application in Home Appliances and Smart Home:

Washing Machine: A limit switch is installed on the door of a front-loading washing machine. The appliance will only start when the door is completely closed and the switch activates the circuit, which prevents water leakage or clothes from being thrown out during operation.

Refrigerator/Oven: When a refrigerator door is closed, the switch triggers to turn off the interior light. Conversely, if an oven door is not securely shut, the switch will cut power to the heating elements to prevent heat leakage.
