SGLW26

A rotary switch enables circuit control through handle-driven contact engagement/disengagement or multi-path switching. Its cam transmission mechanism ensures reliable contact connection/separation, while ratchet positioning provides tactile position feedback. Designed for motor control and instrumentation monitoring scenarios, this mechanical structure guarantees operational precision and electrical safety.

Handles 10A-315A switching for diverse industrial loads
Integrated lockable grey front plates prevent accidental operation
Operates reliably at -25°C to +40°C with ≤90% humidity tolerance
Compatible with M0-M4 panel cutouts for seamless cabinet mounting
690V isolation via reinforced air gaps and creepage protection

Description

SGLW26 Series Rotary Switches deliver 10A to 315A current capacity at 690V rated insulation voltage, supporting 1P to 4P pole configurations for versatile circuit control under 240V/440V operational voltage. Featuring black thumb grip handles with padlockable grey front plates, they enable 0-1 SPST and 1-0-2 SPDT switching modes while complying with IEC 60947-3/5-1 standards and CE certification. With IP20 protection, -25°C to +40°C operation, and panel mounting options M0-M4, they ensure reliable performance in motor starter cabinets, instrumentation circuits, and marine power distribution systems.

To ensure long-term stable operation, systematic periodic maintenance is required: Before operation, de-energize and lock out circuits; verify residual voltage <50V. Clean housing with a slightly damp cotton cloth, avoiding liquid ingress. Quarterly: inspect silver alloy contacts, remove oxidation with specialized rods; replace if pitting （>0.5mm）. Install anti-condensation devices when humidity （>80%）; in dusty areas, clean monthly with ≤0.3MPa air gun. Enforce load current ≤80% rated value; prohibit （>270° rotation）. Annually test insulation resistance with 500V megger (≥100MΩ); replace immediately if contact resistance （>200% initial value or insulation <10MΩ）.
