Safety Switches
The Safety Switches category stocks over 900 safety-rated interlock and guard-monitoring devices used by machine builders, controls engineers, and panel integrators to protect personnel and meet machinery safety standards such as ISO 13849 and IEC 62061. Common device types include tongue (key) interlock switches for guarded access doors, hinge-mounted safety switches for hinged guards and enclosures, and non-contact magnetic interlock switches for applications requiring frequent or high-cycle actuation. Contact configurations typically range from single N.C. safety circuits to multi-channel N.C./N.O. arrangements, supporting PLd/PLe safety integrity levels and dual-channel wiring schemes. Devices are available in plastic and metal-head housings with various actuator styles, quick-disconnect or hardwired terminations, and catch-kit options. These switches are essential components in safety-rated control circuits for robotic cells, packaging machinery, conveyor guarding, and hazardous-energy isolation systems.
