In industrial settings where milliseconds matter, safety systems demand components that prioritize reliability, visibility, and rapid response. The Emergency Switches Metal Push Button Switch Dustproof Red Mushroom Head Emergency Stop Button 3-220V stands as a critical safeguard, engineered to halt machinery instantly in emergencies while enduring the harshest operational conditions. With its iconic red mushroom head, industrial-grade materials, and versatile electrical compatibility, this switch redefines workplace safety for factories, power plants, and automated production lines.
Core Features:
1.Instant-Action Mushroom Head Design
The large, red mushroom head (Ø38mm) ensures quick identification and ergonomic operation. Its palm-activated shape allows operators to trigger an emergency stop with minimal force, even while wearing gloves.
2.Dustproof & Corrosion-Resistant Construction
Featuring a chromium-plated brass or SUS304 stainless steel shell, the switch resists abrasive dust, moisture, and chemical exposure. Sealed terminals prevent particulate ingress, maintaining functionality in foundries, woodshops, or outdoor installations.
3.Broad Voltage Compatibility (3-220V)
With a rated insulation voltage of 250V, the switch integrates seamlessly into low-voltage control circuits (e.g., PLCs) or higher-voltage industrial machinery, eliminating the need for multiple safety components.
4.Dual Contact Configurations (1NO/1NC or 2NO/2NC)
Versatile wiring options support fail-safe systems, enabling simultaneous signal interruption and alarm activation. Silver-plated contacts ensure minimal resistance (≤50mΩ) and long-term conductivity.
5.Self-Locking Mechanism
Once engaged, the mushroom head remains locked in the “stop” position until manually reset, preventing accidental reactivation during troubleshooting.
Technical Breakdown: Precision Engineering for Critical Moments
– Robust Mechanical Endurance
Rated for over 1 million mechanical cycles, the switch withstands repetitive emergency activations without degradation. Its stainless steel spring ensures consistent tactile feedback.
– High-Temperature Resilience
Operates reliably in environments ranging from -20°C to +55°C, making it suitable for furnaces, engine rooms, or refrigerated warehouses.
– Secure Mounting
The M22 ×1 threaded base allows tool-free installation into standard industrial panels. An 8mm shell length ensures compatibility with thick enclosures.
– Low Maintenance
Self-cleaning silver contacts resist oxidation, while the nickel-plated brass terminals prevent corrosion, reducing lifecycle costs.
Applications:
1.Robotics & Automation Lines
Immediately halt robotic arms or conveyor belts during malfunctions, protecting personnel and equipment.
2.Heavy Machinery
Integrate into CNC machines, presses, or crushers to prevent catastrophic failures caused by jams or overloads.
3.Energy & Utilities
Deploy in wind turbines, substations, or pipeline controls to isolate power during leaks or surges.
4.Marine & Offshore Platforms
Saltwater-resistant stainless steel variants ensure reliability in ship engine rooms or oil rig control panels.
5.Food Processing Facilities
Hygienic SUS304 shells meet FDA standards, resisting frequent washdowns without corrosion.
Competitive Advantages Over Generic E-Stop Buttons
-Dual Signal Output Flexibility
Choose between 1NO/1NC (11 contact configuration) or 2NO/2NC (22 configuration) to interface with safety relays, alarms, and PLCs simultaneously.
-Global Certification Compliance
Meets CE, UL, and RoHS standards, ensuring compliance in North American, European, and Asian markets.
-Customizable Locking Mechanisms
Optional key-release or twist-to-reset designs prevent unauthorized reactivation in high-security environments.
-Enhanced Visibility
The bright red head meets ISO 13850 safety color standards, while optional LED illumination improves visibility in dimly lit areas.
