Technical Specifications Rated Insulation Voltage: 690 VAC Rated Thermal Current: 20 A Contact Groups: multi‑pole independent contact stacks Mounting: cabinet front‑panel cut‑out mounting Front‑panel Protection Degree: IP65 Operation: rotary manual handle Operating Temperature: ‑25 ℃ to +70 ℃
Functional Features Multiple rotary gear positions realize different circuit combination logic. Independent contact groups complete signal switching for control loops. Precision cam mechanism guarantees accurate contact action at each gear. High front‑panel protection grade adapts harsh workshop environment. Modular stacked contact structure supports various circuit requirements.
Application Scenarios Local‑remote‑test mode selector switch for motor control cabinet. Multi‑loop signal switching for machine‑tool operation panel. Gear selection switch for field local operation box. Manual transfer switching for instrument measuring auxiliary circuit.
Performance Parameters Clear mechanical positioning for every rotary position. Contact groups strictly follow cam profile to execute switching action. Stable contact performance after large amount of mechanical operation cycles.
Material Composition Flame‑retardant insulating main housing. Metal rotary shaft and cam mechanical assembly. Silver‑alloy contact components. Front‑panel sealing rubber ring. Rear‑side screw wiring terminals.
Structural Features Front‑panel mounting flange with fixing accessories. External rotary operating handle. Internal stacked multi‑pole contact chambers. Rear‑facing screw terminals for control circuit wiring.
Working Principle Rotating front‑panel handle drives inner cam shaft rotation. Cam contour pushes or releases contact spring assemblies. Each rotary gear achieves predefined on‑off combination for every contact group.
Installation Requirements Install switch through reserved opening of cabinet front panel. Secure mounting flange firmly. Carry out rear‑side wiring strictly according to official contact logic diagram.
Usage Notes Load current must not exceed rated thermal current of contacts. Check contact action logic and gear positioning during equipment commissioning. Keep front‑panel sealing rubber intact to maintain IP protection performance.
