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.

Questions about this item

Does the ZB4BC2 mushroom push button include the contact block and mounting hardware, or must they be purchased separately?

The supplied unit is the 40 mm mushroom head operator only; contact blocks, mounting collars and any legend plates are sold separately.

How do I choose between the NEMA 1, 2, 3, 4, 4X, 13 ratings and the IP66, IP67, IP69, IP69K ratings for my application?

NEMA ratings cover indoor and outdoor environmental protection including water and corrosion; the IP ratings confirm resistance to powerful water jets, temporary immersion and high-pressure high-temperature wash-down — select the set that matches your enclosure requirements.

What does the 40 mm mushroom head diameter mean for glove operation and emergency-stop visibility in a real panel?

The 40 mm head provides a large target that is easy to actuate with gloved hands and highly visible for emergency-stop functions, while the 22 mm mounting cut-out fits standard industrial panel layouts.
