Core Features

1. Emergency Stop Safety Protection
   
   
   Bright red mushroom head design for easy identification and operation in emergencies. Latching mechanism keeps the switch locked after pressing, preventing accidental reset, ensuring equipment safety.
2. Modular & Easy Maintenance
   
   
   Split design of button head and contact base, allowing quick replacement of components without disassembling the entire switch, reducing maintenance time and cost.
3. High-Quality Contacts & Conductivity
   
   
   High-thickness silver alloy contacts and copper conductors provide excellent electrical conductivity, low contact resistance, and long service life, ensuring stable performance in industrial environments.
4. Universal 22mm Mounting
   
   
   Standard 22mm panel cutout, compatible with most industrial control panels and enclosures, easy to install and replace.
5. Multiple Contact Options
   
   
   1NO+1NC dual contacts, supporting flexible wiring for different control circuits (NO for status indication, NC for emergency stop control).
6. Durable & Flame-Retardant Construction
   
   
   Flame-retardant plastic housing with high temperature resistance, impact resistance, and oxidation resistance, meeting industrial safety standards.

Contact Type Explanation

• Normally Open (NO, 3-4 terminals): Normally open circuit, closes when the button is pressed.
• Normally Closed (NC, 1-2 terminals): Normally closed circuit, opens when the button is pressed (used for emergency stop control).
• Momentary vs Latching: This switch is latching type: press to lock, twist to reset.

Application Scenarios

• Industrial machinery, production lines, CNC equipment
• Control panels, automation systems, conveyor belts
• Pumps, fans, winches, and other motor-driven equipment
• Emergency stop safety protection for various industrial and commercial equipment

Important Notes

• Wiring: Follow the wiring diagram for correct connection of NO/NC contacts.
• Installation: Must be installed with a heat-resistant, flame-retardant panel.
• Maintenance: Regularly check the contact status and button operation to ensure safety.
