- Description
The Schneider Electric XB7NA42 is a Harmony XB7 monolithic push button for 22 mm panel cutouts on machine control stations. The red flush unmarked operator returns by spring, switches a 1 NC slow-break contact, and wires through screw-clamp terminals, with an IP65-rated plastic body (UL type 3/12) for dusty or washdown environments.

Selection Notes
The 1 NC contact fits the XB7NA42 for a stop or interlock circuit that must open on operator press, and the red cap follows Harmony's usual colour convention for that function. Its screw-clamp terminals accept field wiring without crimped Faston tabs, which simplifies retrofits into panels already wired with ferruled leads, and the flush profile keeps the button recessed to resist accidental actuation on crowded control stations.
