Technical Specifications Rated Insulation Voltage: 690 VAC Rated Operational Current: 20 A Pole Quantity: multi‑pole contact groups Mounting Form: cabinet front‑panel cut‑out mounting Front‑panel Protection Degree: IP65 Handle Operation: rotary manual operation Operating Temperature: ‑25 ℃ to +70 ℃
Functional Features Multi‑pole contact groups for power or control circuit switching. Precision cam mechanical structure ensures accurate contact action at each position. Front‑panel rotary handle for direct local manual operation. High front‑panel protection grade adapts workshop dusty environment. Modular contact stack structure for different circuit logic combination.
Application Scenarios Manual transfer switch for pump and fan control cabinet. Local‑remote mode selection switch for industrial equipment operation panel. Circuit change‑over switch for power distribution auxiliary loop. Multi‑position selection switch for machine‑tool and process equipment.
Performance Parameters Distinct mechanical positioning for each operation gear. Contact switching capacity meets low‑voltage power and control circuit requirement. Mechanical wear resistance satisfies frequent manual operation condition.
Material Composition Flame‑retardant insulating main housing. Metal rotary shaft and cam mechanical assembly. Silver alloy contact sets. Front‑panel sealing rubber ring. Rear‑side screw terminal blocks.
Structural Features Front‑panel mounting flange with fixing hardware. Rotary operating handle assembled on front face. Stack‑type multi‑pole contact chambers inside housing. Rear‑facing screw terminals for circuit wiring.
Working Principle Manual rotation of outer handle drives inner cam shaft. Cam contour acts upon contact spring assembly. Each rotary position achieves fixed on‑off status for each pole contact group.
Installation Requirements Fit switch body through cabinet front‑panel reserved cut‑out hole. Secure mounting flange tightly against cabinet panel surface. Complete rear‑side wiring strictly according to contact logic drawing.
Usage Notes Do not apply load current exceeding rated operational current. Confirm each gear contact logic matches design requirement in commissioning. Maintain sealing ring integrity to guarantee front‑panel IP protection grade.
