Schneider Electric ZB4BC2 40 mm Mushroom Push Button 22 mm Black

22 mm Mushroom Push Button

The Schneider Electric ZB4BC2 is a 22 mm mushroom head push button designed for industrial control panels. Its momentary action suits start, stop or emergency functions in machinery and automation systems. The 40 mm metal head and metal bezel provide mechanical durability in demanding environments. The black finish gives clear visual identification on crowded panels.

Panel cut-out and environmental rating

Verify that the mounting surface has a standard 22 mm cut-out before ordering. The operator carries NEMA 1, 2, 3, 4, 4X and 13 ratings alongside IP66, IP67, IP69 and IP69K sealing. These ratings confirm suitability for wash-down, dust and high-pressure water exposure. No legend plate is included, so plan for separate marking if required.

Replaces worn or smaller operators

This unit replaces damaged or undersized push buttons in existing 22 mm cut-outs. The upgrade is worth it when a larger 40 mm mushroom head improves operator reach or visibility. Metal construction replaces plastic heads that crack under impact or UV exposure. The broad NEMA and IP coverage consolidates sealing requirements that previously needed multiple specialised parts.
