4. Why Choose This Switch Series?
🔵 High Insulation Voltage – 690V Rated
With a rated insulation voltage of 690V, this switch is suitable for industrial control circuits up to 690V AC, meeting the requirements of most factory automation and machinery applications.
🟢 Flexible Wiring Options
The spiral embedded terminal design accepts:
Minimum wiring: 1 × 0.5mm²
Maximum wiring: 2 × 1.5mm² or 1 × 2.5mm²
This allows easy integration into existing control panels without special tools or adapters.
🟡 Long Mechanical and Electrical Life
Flat / Mushroom / Lamp heads: 1,000,000 mechanical cycles – built for high-frequency operation
AC electrical life on flat/mushroom heads: 500,000 cycles – reliable switching under load
🔴 Emergency Stop (E-stop) Configuration Available
The red maintained flat emergency stop switch with LED lamp is designed for safety-critical applications:
Maintained action – Stays in the pressed position until manually reset
Red color – High visibility for emergency situations
LED lamp option – Visual indication of switch state
22mm standard mounting hole – Compatible with existing panel cutouts
📊 Protection Grade Options
Standard: IP40 – protection against solid objects >1mm
Optional: IP65 waterproof button – dust-tight and protected against low-pressure water jets (washdown capable)
5. Rotary Switch (Non-Illuminated Knob)
For applications requiring mode selection or multi-position control:
| Feature | Description |
|---|---|
| Illumination | Non-illuminated (standard) – suitable for daytime/well-lit panels |
| Knob Type | Rotary knob – easy to grip and turn |
| Applications | Hand/off/auto selection, speed control, mode switching, manual override |
6. Typical Applications
This 22mm switch series is ideal for:
Industrial machinery control panels (lathes, mills, presses, conveyors)
HVAC systems – mode selection, on/off control
Packaging equipment – emergency stop, cycle start
Food processing lines – with IP65 option for washdown environments
Material handling systems
Automated production lines
Safety circuits – emergency stop integration
7. Installation and Wiring
Mounting hole diameter: 22mm (standard industrial size)
Terminal type: Spiral embedded terminal – secure, vibration-resistant connections
Wiring Example (AC-15 @ 220V 6A):
Use 1.5mm² copper wire (solid or stranded)
Strip 6-8mm of insulation
