Product Overview

LW12 series universal rotary changeover switch is a classic cam‑type control component widely used in low‑voltage industrial control systems. By rotating the operating handle, internal cam mechanism drives contact groups to realize different circuit switching logic.
It can complete manual‑auto mode switching, circuit transfer, signal conversion, motor local/remote selection and other control functions. Adopts high‑performance silver‑alloy contacts and thick copper conductive components, guarantees stable electrical performance for long‑time operation. Flexible multi‑gear customization meets diverse control logic requirements. It is a standard fitting inside power cabinets, PLC control panels and various mechanical equipment worldwide.

Key Product Features

Silver‑Alloy Electrical Contacts

High‑quality silver alloy contacts, excellent arc‑resistance and anti‑ablation performance. Stable contact conductivity, reduce contact heating risk, extend service life for frequent switching operation.

Thickened Copper Conductive Components

Conductive terminals adopt thick copper material, low resistance, good current‑carrying capacity, reliable connection under rated current.

Flexible Multi‑Gear & Multi‑Pole Custom Logic

Support different gear‑position combinations: 2‑position, 3‑position, multi‑position. Multiple pole options for diverse control logic, such as manual‑auto, on‑off‑reset, multi‑loop signal transfer.

Simple Panel‑Mount Installation

Standard panel cut‑out size, front‑panel mounting structure. Easy assembly on control cabinet door, compact structure saves cabinet inner space. Rotation handle operates smoothly with clear gear‑position feel.

High‑Strength Insulating Housing

Flame‑retardant insulating material, good dielectric property, anti‑aging, adapt to workshop normal industrial environment.

Wide Specification Coverage

Multiple rated current options available, cover small‑signal control up to main‑loop auxiliary‑circuit switching for distribution equipment.

Clear Visual Operation Handle

Human‑friendly rotary handle, obvious position indication. Operators can quickly identify current switch gear status.
