safety interlock switches -1
The Safety Interlock Switch is a critical device for machine guarding. It prevents machine operation unless a safety gate or guard is securely closed. If the guard is opened, the switch sends an immediate stop signal, preventing access to hazardous areas and ensuring operator safety.
