Product Overview
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.
