"Safety switches with separate keyed actuators provide a failsafe switch function, indicating the position of guarding access points. These are typically used on hard guarding gates, panels and doors. The switches are normally mounted on the fixed frame of the machine. The actuator key mounts on the door. When the door is closed the key is inserted into the switch, closing the normally closed safety contacts."

"Due to inertia some machines may continue to run after their power is removed. This can create a situation where it is possible to access the hazardous areas of the machine when they are still in a dangerous state. The solution to this problem is to lock the hard guarding access door closed until the machine is given enough time to wind down. The SLK and SLM series have a built in solenoid which can lock (or unlock) the activation key into the switch, preventing the door or gate from being opened."

"Non-Contact Safety Switches are easy to install and offer wear free, control reliable switching which is vibration resistant and easy to clean. Both magnetic and RFID versions are available. The RFID types are available in unique or multiple coding with on board diagnostics. These units offer an OSSD solid state output, which can be used with a safety relay or for standalone applications. Remote monitoring through a separate diagnostic channel is available. Up to 32 switch can be run in series using plug in connectors."

"Safety Hinged Switches combine the function of a load bearing hinge with a Category 4 (Ple) rated safety switch. They are easy to install and tamper resistant. Since they do not use an actuation key, there are no alignment or bend radius issues and they cannot be defeated with an extra key. The SHS series is available with 1 NC or 1 Changeover contact. The new SHS3 offers 2 NC\/1 NO contacts. Safety Hinged switches are available with the cable attached or with an M12 connector."
