When safety is not optional, control must be absolute.
This 22mm Mushroom Head Emergency Stop Push Button Switch is engineered for rapid interruption of power circuits in industrial control panels, machinery stations, packaging lines, automation cabinets, and electrical enclosures. The mushroom head design offers an expanded surface area, allowing operators to strike the button instantly—even with gloves or under stress.
The red version signals emergency shutdown in accordance with industrial safety conventions, while the green sign version can be used for controlled stop functions or specific system logic. The matte surface resists glare under workshop lighting, and the slightly textured cap provides confident grip without slipping.
Internally, the contact mechanism is precision-assembled to ensure low contact resistance and stable conductivity. The push-lock structure produces a firm, mechanical “click” when activated. Twist-to-release action prevents accidental reset and ensures only intentional restoration of operation.
From high-vibration machinery environments to compact control cabinets, the IP65-rated front panel sealing protects against dust ingress and water splashes, maintaining reliability in demanding conditions.

The housing is molded from high-strength flame-retardant material, engineered to withstand impact and resist deformation. Even in high-vibration equipment panels, the switch remains securely seated.
Silver alloy contacts reduce arcing and minimize oxidation. The result is consistent switching performance and reduced maintenance frequency.
Red mushroom head aligns with international emergency stop conventions, helping reduce human error in urgent scenarios.
The twist-to-release structure requires deliberate action, preventing unintended restart after shutdown.

Our production process follows strict internal quality management protocols to ensure stable batch consistency and performance reliability.

The red mushroom head version follows common industrial safety identification standards for emergency stop functions and supports latching stop mechanisms widely used in industrial environments.
The front panel is IP65-rated, offering protection against dust and water splashes. For full outdoor exposure, additional enclosure protection is recommended.
1NO1NC provides one normally open and one normally closed contact. 2NC provides two normally closed contacts, commonly used in safety circuits.
No. It resets by manual twist after pressing, ensuring controlled restart without tools.
Yes. The modular structure allows replacement or configuration changes depending on application needs.
