A safety door lock switch is a unique safety device that integrates door interlocking and safety monitoring. It ensures that no machinery can function unless the safety door is locked and closed securely, preventing any operational issues. The switch employs electromechanical or magnetic locking mechanisms, with contacts verifying both the position of the door and the locking status. This type of lock has CNC machines, industrial presses and ovens, and specialized prevention of access to dangerous zones as primary targets. Some models are equipped with key-release mechanisms to allow maintenance access, while others integrate into a PLC for remote door status monitoring.
