Selection Notes
Two independent NC contacts with key release suit dual-channel safety circuits where reset authority also needs to be restricted, combining the logic of the turn-to-release XALK178F with a secured reset. Where a single safety circuit and key release is enough, the XALK188 is the leaner option.
