Rotary switch What it does Provides reliable, manual selection between multiple electrical circuits or settings by rotating a knob or shaft to distinct positions. Converts a single control point into multiple selectable outputs or modes without complex wiring or software. Key benefits — why you need it Simple and intuitive control: change modes or inputs quickly with a single, tactile motion. Spaceefficient: replaces multiple switches or complex selector arrangements, saving panel or PCB space. Reliable operation: mechanical switching ensures a clear, repeatable connection state for control and signal routing. Flexible integration: suitable for applications that require manual selection of ranges, sources, or operating modes, subject to matching electrical and mounting requirements. Important attributes to check Function: multiposition on/off or changeover switching; exact number of positions and contact configuration vary by model. Compatibility: designed for panelmount or PCB integration; ensure the switch's electrical ratings (voltage, current), shaft type, and mounting dimensions match your equipment. Size and mounting: available in compact formats for spaceconstrained panels and larger formats for industrial use — verify exact dimensions for cutout and depth clearance. Material and build: commonly constructed with metal or durable plastic components and available with various shaft and knob options; consult the product specification for material details. Performance: mechanical actuation provides definitive position detents and contact switching; electrical life and contact resistance depend on the specific model and ratings. Practical applications Industrial control panels: select machine modes, tool ranges, or operational states in factories and equipment rooms. Audio and broadcast equipment: switch inputs or routing paths for mixers, amplifiers, and monitoring systems. Test and measurement: change measurement ranges, signal paths, or configuration presets on laboratory instruments and bench equipment. How to choose the right rotary switch Match the electrical ratings (voltage/current) to your circuit to ensure safe, longlasting operation. Confirm the number of positions and contact arrangement (e.g., singlepole, multipole) required for your wiring scheme. Verify physical dimensions, shaft type, and mounting style to ensure fit and ergonomic control on your panel or PCB. Review environmental and mechanical specifications (operating temperature, IP rating if needed, and expected lifecycle) for the intended application. Installation and maintenance notes Follow the manufacturer's wiring diagram and torque specifications for terminals. Provide appropriate strain relief and clearance for mounting depth. Inspect contacts and mechanical operation periodically in use or harsh environments; when electrical performance degrades. For exact specifications, dimensions, materials, and available models, refer to the product technical datasheet or the specific model listing.
