New Idec interlock safety switches feature six contacts with easy-to-wire termination and an increased locking force of 3,000N. HS1L switches are designed to work in applications 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. Screw terminals are easy to wire. No barriers on the sides of the contact terminal also enable wiring from the side.
