An important machine safeguarding device is a safety switch or also know as a safety interlock switch which interlocks a guard door with the power source of the hazard. Safety switches are available in a wide variety of models to satisfy most machine guarding applications. Safety switch models range from rope operated emergency stop switches, non-contact magnetic and hinge-pin operated safety interlock switches to solenoid actuated guard-door locking safety switches that restrict access until safe conditions exist.

All Omron Scientific Technologies, Inc. models of safety switches conform to applicable U.S. safety standards and all carry the CE mark.
