3. Why Choose the 16M Waterproof E-Stop Button?
🔵 IP67 Waterproof Protection
The button end is rated IP67, meaning it is completely dust-tight and can withstand temporary immersion in water. Perfect for outdoor kiosks, marine equipment, food processing, and automotive applications.
🟢 High Current Rating – Up to 5A
Unlike many small emergency buttons that only handle low current, the 16M supports resistive loads up to 5A at 250V AC, making it suitable for direct control of small to medium power circuits.
🟡 Multiple Contact Options
Available in 2NO, 2NC, or 1NO1NC configurations. Whether you need a single safety circuit or a dual-channel monitoring system, this switch has you covered.
🔴 Durable Materials for Long Life
Housing Material: Modified nylon PA66 – strong, heat-resistant, and flame-retardant
Contact Material: Silver tin oxide alloy – ensures low contact resistance (<50mΩ) and high durability
Button Material: PA66 nylon – impact-resistant for repeated emergency presses
📊 Long Electrical Life
Tested for >100,000 electrical cycles under rated load (DC-13: 12V/24V 5A / AC-15: 110V/220V 5A). You can trust this switch to work when you need it most.
🎨 Customizable Key Head Types
The button head can be customized with various markings:
STOP (standard)
Arrow-marked
Pointed / Lighted
Custom logo or text (OEM available)
4. How It Works – Switch States
| Action | 2NC | 2NO | 1NO1NC |
|---|---|---|---|
| Button Pressed (Emergency) | NC contacts open | NO contacts close | NO closes / NC opens |
| Button Released (Reset) | NC contacts close | NO contacts open | NO opens / NC closes |
For self-locking type: Rotate the button clockwise to reset after pressing.
For self-resetting type: Button automatically returns when released.
5. LED Lighting Options (For Illuminated Versions)
