LW26-63A Universal Changeover Switch - Flexible Circuit Switching with Reliable Rotary Control for Industrial Applications

The LW26-63A universal changeover switch is a classic cam-type rotary switch widely used in industrial electrical control systems. With a rated current of 63A, it is suitable for AC circuits up to 440V and DC circuits up to 240V. Its cam-driven mechanism enables manual switching of multiple power sources and motor operating modes, supporting multi-position selection for power source changeover, motor forward/reverse control, signal circuit switching and circuit measurement.

Equipped with silver alloy contacts, the switch offers excellent conductivity and reliable arc suppression, with a mechanical life of up to 100,000 operations. Even after repeated rotary switching, it maintains stable make-and-break performance without poor contact. The housing is made of high-strength insulating material with outstanding dielectric properties. The compact panel-mount design features a standard 64×64mm panel size for easy cabinet cutout installation; the knob provides clear position indication, smooth rotation and firm positioning to prevent accidental switching.

Widely applied in machine tools, pump stations, welding machines, distribution cabinets and testing equipment for infrequent circuit making and breaking, power source selection, motor start/stop and reversing, and signal circuit switching. Compliant with industry electrical safety standards, resistant to aging and workshop dust, it serves both as a replacement for older changeover switches and as a suitable component for electrical control retrofitting of automation equipment. It is a cost-effective circuit switching component for industrial complete sets and machinery electrical control, providing a safe and stable switching solution for equipment circuit control.
