China Emergency Stop Button with Key Manufacturer, Supplier, Factory

Industrial safety systems demand components that deliver unwavering reliability under the most challenging conditions. Our Key-Release Emergency Stop Button is engineered to provide immediate machine shutdown with a twist-to-release mechanism that prevents accidental restart, ensuring operator protection in factories, packaging lines, and automated assembly cells. For applications that require restricted access and absolute control, the Key Lock Emergency Stop Button adds an extra layer of security by keeping the stop function engaged until an authorized key is used. Both configurations are built around a rugged metal housing and high-contrast red mushroom head, meeting ISO 13850 and IEC 60947-5-5 standards with a direct opening mechanism that guarantees contact separation even if the contacts are welded. With IP65 front-panel sealing, wide operating temperature ranges from -25°C to +70°C, and a choice of 1NC or 2NC contact blocks, these emergency stop buttons integrate seamlessly into safety relay circuits, PLC guard control, and standalone E-Stop chains.

The Emergency Stop Button with Key merges fast, intuitive manual operation with managed override capabilities that modern production environments require. Its ergonomic actuator is designed for palm or finger strike, reducing reaction time during critical events, while the key-release feature makes deliberate resetting straightforward for maintenance personnel. The durable thermoplastic and metal construction withstands high vibration, impacts, and chemical exposure, making it suitable for heavy machinery, conveyor systems, and outdoor equipment enclosures. A yellow bezel or legend plate provides high visibility even in poorly lit areas, and the snap-action contacts deliver a positive tactile response, so operators know instantly that the command has been registered. Whether you need to retrofit a legacy panel or design a new safety architecture from the ground up, this device offers flexible mounting options including 22 mm panel cutouts and convenient rear-terminal wiring with clearly marked numbering.
