Selector switch What it is A manual multiposition switch used to route power or signals within control panels and equipment. It provides a clear, singlepath selection among several circuit options. Why you need it Simplifies wiring by consolidating circuit routing into one control Enables quick changes of mode, source, or setting without rewiring Delivers reliable, repeatable position selection for consistent operation How it works A common terminal is connected to one of several outputs depending on the chosen position of the actuator. Each model offers a different number of positions and actuator styles. Key attributes to consider Function Selects one of multiple circuits or settings in a single action Compatibility Designed for standard control panels and equipment; compatibility with common panel cutouts, wiring schemes, and terminal blocks varies by model Size Compact panelmount form factor; exact dimensions depend on configuration Material Housing materials vary by model (typically thermoplastic or metal); contact materials and finishes are specified per model Performance Built for dependable mechanical action and durable electrical contact; electrical ratings and life expectancy are model dependent Configurations and options (modeldependent) Number of positions (two or more) Actuation style (rotary, pushpull, or other designs) Mounting method (panel mounting or chassis mounting) Contact arrangement and terminal type Environmental ratings (as applicable to the model) Use scenarios (practical applications) 1) Industrial machine control panel: switch between automatic and manual operation or select different process modes. 2) Audio/lighting rack: choose between input sources or lighting scenes to streamline setup and operation. 3) Lab equipment or test bench: toggle between measurement ranges or test configurations for quick comparisons. Installation and setup ( level) Identify the required number of positions, actuator style, and mounting type from the model specification Confirm electrical ratings match your system requirements Install in the panel cutout, secure mounting, and connect terminals per wiring diagram Test operation across all positions to verify correct routing and safe operation Maintenance and care Keep the actuator and contact surfaces clean and dry Inspect for wear or corrosion during routine maintenance with the exact model or equivalent specification to maintain performance and safety Summary A selector switch offers a reliable, straightforward means to select among multiple circuit paths in a compact, panelfriendly package. Modeldependent specifics such as number of positions, actuator type, materials, and electrical ratings should be verified on the product datasheet to ensure exact fit and performance for your application.
