Selection Notes

Two independent NC contacts plus the illuminated-ring NO signal make this the choice for dual-channel safety wiring that also needs a live status indication, over the single-NC XALK178W3B140E sibling. Specify it wherever the machine safety circuit requires two separate monitored stop paths from one illuminated button.
