A mushroom button switch is a large, round push button typically used for emergency stop (E-stop) or high-visibility control functions in industrial and commercial settings. Named for its wide, dome-shaped top, it’s designed to be easily hit in a hurry, even with a fist or elbow.
Because in an emergency, speed and clarity matter. Its oversized, brightly colored (usually red or yellow) head makes it instantly recognizable. Most are latching-type switches, meaning they stay locked in the "off" position until manually reset—ideal for halting machinery or power in hazardous situations.
Key features often include:
Momentary or maintained action
Twist-release or key-reset mechanisms
Panel-mount or enclosure-mount designs
Compliance with safety standards like IEC or UL
Commonly used in manufacturing lines, elevators, automation systems, and control stations, mushroom switches enhance both safety and usability.
In short, a mushroom button switch is a simple yet crucial safeguard—big, bold, and always ready to stop trouble with a single push.
