ON‑OFF‑ON 3‑position selector switch — 18 terminals — universal changeover Key benefits Clear, predictable control: three distinct selector positions (ON — OFF — ON) let you switch between two active circuits with a center-off for safe neutralization. Versatile wiring options: 18 terminals support multi-pole or complex changeover wiring, reducing the need for additional switchgear. Universal changeover function: designed for a wide range of switching tasks, so one component can serve many roles across systems. Simplifies panel design and maintenance: a single selector handles multiple routing needs, making wiring and troubleshooting more straightforward. What it does (function and performance) Acts as a three-position selector switch with changeover capability: choose between two outputs/inputs or isolate the circuit in the center OFF position. 18 terminals provide flexible contact configurations for multi-circuit control and common changeover arrangements. Reliable, repeatable position switching for consistent control operations. Compatibility and typical attributes Universal changeover design: suitable for use in control panels, electrical systems, and equipment that require selectable routing or mode selection. Works wherever an ON‑OFF‑ON selector is required; supports a range of wiring schemes because of its 18-terminal layout. Intended for practical switching applications rather than a single-purpose device. Practical use scenarios Motor direction or mode selection: use the two ON positions to select forward or reverse lines and the center OFF to stop or isolate the motor. Source or path selection: switch between two power sources or signal feeds with the center OFF for safe transition or maintenance. Equipment or signal routing: select between two inputs or outputs in control panels, audio/video routing, or test setups while keeping circuits isolated when needed. Why choose this switch Provides a straightforward ON‑OFF‑ON changeover in one compact control. 18-terminal layout enables flexible wiring for multiple poles and contact arrangements. A universal option that fits a variety of switching needs without requiring added components. Includes only the stated features: ON‑OFF‑ON 3-position selector, 18 terminals, universal changeover switch capable of a wide range of switching applications.
