Interlock safety switches

The HS1L interlock safety switches are designed for use with large machines that have heavy doors or gates and are equipped with a manual lock-release key and an LED indicator. The indicator is wired independently, for added flexibility. The switches feature six contacts with easy-to-wire termination and a 3,000-N locking force.

No barriers on the sides of the contact terminal permits wiring from the side. The HS1L significant height difference at contact terminals makes it easier for crimp-terminal connections.
