Emergency Stop Button 22 mm
The Schneider Electric XB4BS8442 is a maintained-action emergency stop push button designed for industrial safety circuits. Its 22 mm mounting diameter fits standard panel cut-outs, and the red 40 mm mushroom head provides clear actuation in urgent situations.
Contact Rating and Environmental Sealing
A single normally closed contact rated at 10 A at 600 V AC handles typical control-circuit loads. The head carries NEMA 12, 13, 4 and 4X ratings plus IP66, IP67, IP69 and IP69K, so it withstands high-pressure wash-down and dust ingress. The chrome-plated zinc die-cast bezel resists corrosion in harsh plant environments.
Maintained Action Requires Manual Reset
The operator stays latched after actuation and must be turned or pulled to release, preventing accidental restart. Buyers needing momentary or self-resetting operation should select a different device.

Questions about this item
Will the 22 mm mounting fit the panel cut-outs on my existing control board?
The operator is built for a 22 mm panel cut-out and uses a chrome-plated zinc die-cast bezel that matches standard industrial 22 mm mounting holes.
How can I verify the 1NC contact opens when I twist the 40 mm mushroom head?
With power off, attach a continuity tester to the contact terminals; the circuit should show open when the red head is latched and closed again after you pull or twist to reset.
Does the box include a legend plate or only the complete operator with metal head?
The package contains the complete maintained-action operator with 40 mm metal mushroom head, chrome bezel and 1NC contact block; no separate legend plate is included.
