Force-guided relays are used in safety circuits in combination with interlock switches, light curtains, and emergency stop switches to control outputs. Contacts of a force-guided relay are forced to open and close by a guide connected to the armature. A force-guided relay has independent NO and NC contacts. If a NO contact welds, an NC contact will not close even when the relay coil is turned off (de-energized). If an NC contact welds, a NO contact will not close when the relay is turned on (energized). For example, a failure of an NO contact to open (by welding closed) is identified by the failure of the NC from closing, thereby signaling an operational anomaly.
