A 22 mm metal emergency-stop push button with a 30 mm mushroom head and IP66 protection
This Schneider Electric emergency stop push button uses a 22 mm mounting diameter and a 30 mm metal mushroom head. The maintained operator stays latched until deliberately reset. All exposed components are metal for durability in industrial control panels.
Upgrade when an existing button shows corrosion, cracked actuators or lost IP sealing. The metal bezel and head resist impact and chemical exposure better than plastic alternatives. The jump is worth it when the panel must meet NEMA 1, 2, 3, 4, 4X and 13 ratings.
The operator fits only panels drilled for a 22 mm opening and cannot be adapted to 30 mm or other standard sizes without a new enclosure. IP66 protection applies only when the head is correctly seated and the panel surface is flat. Buyers who need a different mounting diameter or a non-maintained action cannot use this unit.

The operator mounts in a standard 22 mm panel cut-out and is secured with the supplied locking nut.
Align the head with the base, press it on, then rotate until it locks into the maintained position; skipping the rotation leaves the button unlatched.
Inspect the red mushroom head and metal bezel periodically for corrosion or impact damage; replace the complete operator if the head no longer latches or the seal is compromised.
