Three-Position Double Latching Rotary Selector Switch Head

Product Overview

Manufactured by Jiangsu ACXION (China), this Three-Position Double Latching Rotary Selector Switch Head is a high-durability operator actuator engineered for multi-state industrial control panels. Built as a front-panel component, it features a self-locking maintained mechanism that holds firmly in three distinct positions (Left – Center – Right / I – O – II). This ensures stable mode selection and signal retention under heavy machine vibration without including underlying electrical contact blocks.

Key Features

• Maintained 3-Position Retention: Securely stays in any selected state (I – O – II) until manually turned, eliminating unexpected signal loss or accidental position shifts from industrial shock and vibration.
  Anti-Rotation Chassis Alignment: Built with an anti-torque guide tab that keys into panel cutouts, preventing housing slippage and loosening under heavy manual torque.
  High-Frequency Fatigue Resistance: Engineered for high-cycle industrial panels, offering durable long-term performance under continuous manual operation.
  Dust & Moisture Resistance: Built to withstand harsh factory environments, protecting internal mechanical assemblies from dust ingress, oil mist, and liquid splashes.

Complete Switch Assembly Reference

If your control panel requires the full switch assembly pre-fitted with dual Normally Open (2NO) contact blocks rather than just the actuator head, please see our standard complete model:
