2NO Three-Position Double Latching Rotary Selector Switch
The ACXION 2NO Three-Position Double Latching Rotary Selector Switch is a high-performance manual control component designed for stable mode selection and circuit state maintenance. Featuring a secure stay-put (maintained) mechanism, this switch locks firmly into each of its three positions (Left-Center-Right). Equipped with a 2NO (Double Normally Open) contact configuration and a 1 million cycle mechanical life, it is the industry-standard choice for Manual-Off-Auto transitions in power distribution and automated production lines.
Product Features
Triple-Position Latching Action: The robust stay-put mechanism ensures the knob remains securely in the selected position (I, O, or II), providing constant signal retention for critical system mode switching.
Dual-Circuit 2NO Logic: Features two independent Normally Open contact blocks, allowing for the simultaneous control of two separate circuits within a single modular unit.
Modular Three-Part Construction: Composed of a durable rotary knob, middle base, and contact assembly. The screw terminal wiring design facilitates rapid installation and simplified maintenance.
Anti-Rotation Stability: Equipped with an integrated boss design that fits precisely into the mounting opening, preventing the switch head from shifting or loosening during heavy-duty manual operation.
Rugged Industrial Protection: Standard IP65 rating for superior dust and water resistance (upgradeable to IP66), ensuring consistent performance in demanding indoor and outdoor environments.
Exceptional Service Life: Engineered for long-term reliability with a mechanical life of 1 million cycles, significantly reducing maintenance costs for global engineering projects.
