General description
MKey8 interlock switches are designed to provide position interlock detection for moving guards. They are
designed to fit the leading edge of sliding, hinged or lift off machine guards. The actuator is fitted to the moving part
of the guard and is aligned to the switch entry aperture. The possibility to lock the switch in the protective position
prevents unwanted access to machinery until dangerous operations have ceased.
The locking is useful when applications include:
•
processes which cannot be interrupted, such as welding.
•
machinery with a long stopping procedure, such as paper machinery that requires a long braking operation.
•
prevention of unauthorised access to a particular area.
