Selector switches provide a clear, reliable way to route signals or power between multiple circuits from a single control point. Function: multiposition devices that select one circuit path at a time via a knob or lever, giving precise, repeatable routing. Compatibility: available in multiple pole and throw configurations to fit standard panel cutouts and wiring schemes. Size and material: compact panelmount form factor; durable housings in metal or strength plastic; robust contact methods for long life. Performance: smooth actuation, consistent positional feedback, and dependable operation in typical control environments. Use scenarios: Electronics lab bench: route test signals between sources and measurement equipment during prototyping. Industrial control panel: switch between operating modes or route power to different subsystems. Audio/video or home automation: select input sources or route audio and video signals. Why it matters: reduces wiring complexity, improves control clarity, and offers manual control for critical circuits.
