Safety Switch and Trapped Key Interlock
Safety Switch
Electromechanical safety switches monitor accesses or safety gates. When opening an access the machine switches off immediately.
Electromechanical safety switches are used in different safety areas. The most common applications areas are the protection of movable separating guards, as for example safety gates and covers in machines and plant constructions. When opening the protection guard the dangerous movements must be switched off immediately and be secured against restarting. The hazardous machine will only be put back into operation with the safety guard in closed and locked condition.
