Emergency Stop Push Button Switch 22mm

This DPST Emergency Stop Push Button Switch is a rugged safety component designed for hobbyists and technicians building control panels, DIY machinery, and automation projects. Featuring the classic red mushroom-cap design, this switch provides an instantly recognizable emergency stop point that operators can activate quickly under pressure. The DPST configuration includes one normally open (NO) and one normally closed (NC) contact, allowing it to simultaneously break one circuit and complete another when pressed, making it ideal for cutting power to motors, contactors, relays, and other automated equipment. Its self-locking mushroom cap stays pressed in until manually twisted and released, preventing accidental re-activation of dangerous machinery before the fault is cleared. Built with a durable plastic housing and a 22mm panel mount, this switch installs easily into standard control panel cutouts and pairs well with enclosures for indoor or light industrial use. It’s a practical addition to CNC machines, 3D printers, workshop power distribution boards, robotics platforms, and any DIY project requiring a reliable manual safety cutoff. With its high current and voltage rating, this switch is built to handle demanding electrical loads while providing dependable, fast-acting protection whenever it’s needed most.
