30mm 1NO 1NC 10A 250V Emergency Stop Push Button Switch Explosion-Proof Anti-Corrosion Control Switch 3C Certified EX Rated

Certified Safety for Hazardous Locations, One-Touch Emergency Shutdown
This BA series explosion-proof corrosion-resistant emergency stop button is purpose-built for rapid circuit shutdown in chemical, oil and gas, pharmaceutical and other high-risk industrial environments. It carries complete 3C certification and official EX explosion protection marking, fully meeting both domestic and international industrial safety compliance requirements. Its prominent mushroom head design allows operators to trigger emergency shutdown instantly with a single palm press, no precise alignment required during urgent scenarios.

The latching self-lock mechanism locks the button firmly in the shutdown position after being pressed, preventing accidental reset caused by equipment vibration or unintended touch. To restore operation, simply twist the button head clockwise to release the lock, no extra tools or complex operations needed. This twist-reset design strictly follows global industrial emergency stop safety standards, eliminating the risk of accidental restart before on-site hazards are fully cleared.

Constructed with a reinforced flameproof housing and WF2 corrosion-resistant coating, the unit resists long-term exposure to chemical vapors, salt spray, industrial cleaning fluids and outdoor harsh weather. Its precisely controlled flameproof joint gaps fully block internal electrical arcs or sparks from spreading to the external explosive gas atmosphere, preventing secondary explosion risks even if a fault occurs inside the switch.

With IP65 ingress protection, the button is fully dust-tight and resistant to low-pressure water jet washdown. It operates stably across a -20°C to +70°C wide working temperature range, making it suitable for long-term deployment on outdoor operation columns, explosion-proof control boxes, production line side panels and other exposed industrial positions.

Typical Application Scenarios
This BA series emergency stop button is widely deployed on chemical production lines, oil refinery on-site operation panels, pharmaceutical manufacturing workshops, paint spraying booths, mining surface equipment and large industrial automation production lines. It serves as a direct drop-in replacement for most mainstream 30mm explosion-proof emergency stop buttons, requiring no extra panel modification during installation.

Every unit passes 4 rounds of strict pre-shipment quality inspections, including 3C certification authenticity verification, EX flame gap dimensional check, IP65 water spray test and emergency latching mechanism durability test. We maintain consistent batch quality, fast order fulfillment, and support bulk customization for contact configuration, housing material and marking requirements for large industrial projects.

Replace ordinary non-certified emergency stop switches on your hazardous site with this fully certified model, to meet local safety audit requirements and ensure reliable emergency shutdown performance when it matters most.
