Mushroom Push Button

A mushroom push button is an oversized, dome-shaped switch designed for request-to-exit or emergency egress release, where speed and ease of activation matter more than a compact footprint. Its enlarged surface lets someone hit it with a palm, fist, or elbow rather than needing to precisely target a small button.

Yes, the large mushroom-shaped target is specifically suited to emergencies and users with limited hand dexterity, since it doesn't require fine motor control to activate. This makes it a common choice at exits and egress points where a fast, reliable release is critical.

The mushroom button's large dome shape is built for emergency egress and request-to-exit applications where a big, easy-to-hit target matters, while PDQ's narrow and wide push buttons are flat, trim-plate-sized buttons meant to match a door's stile width for standard door-release use. Choose the mushroom style specifically for emergency or high-urgency release points.

Yes, PDQ offers it in momentary (81320-5MT), where the button springs back after release, and maintained (81320-5MM), where it stays engaged until pressed again. Momentary is standard for exit-release applications tied to a timed unlock cycle.

It has a stainless steel faceplate for durability in high-use, high-traffic commercial entrances such as emergency exits, loading docks, and secured egress doors where the button may be struck frequently or forcefully.
