Coded Rotary Switch

A Coded Rotary Switch is an electromechanical component that selects one of several output channels based on its rotational position. Unlike simple switches, it provides a unique binary-coded output (e.g., Binary or Gray code) for each position, which can be directly interpreted by digital circuits like microcontrollers. This eliminates the need for multiple I/O pins, making it ideal for digital input selection in settings like industrial control panels, audio equipment, and test instruments. Its design ensures precise, reliable digital data entry from a manual rotary control.

  • Application Field

A coded rotary switch is a control component that converts mechanical rotation operations into precise electrical signals. It combines intuitive operation with reliable performance, serving as a core component for device parameter adjustment and function control.


Driven by the rotating shaft, its internal contacts or photoelectric sensors act to output signals such as digital pulses. It can accurately identify the rotation direction and angle to achieve fine adjustment of parameters; some models integrate a pressing function, meeting the dual needs of rotation adjustment and switch control. The product features high resolution and long service life, with a contact resistance as low as below 100mΩ. It can work stably in a wide temperature range from -40℃ to 85℃, adapting to various scenarios.


Widely used in volume adjustment of audio equipment, parameter setting of smart home appliances, precision control of industrial instruments, function switching of automotive electronics and other fields, it enhances the device operation experience through simple and convenient operation.

Precision Engineering

Coded rotary switches utilize Gray code or binary encoding with a typical angular resolution of 22.5° to 90° per detent, ensuring unambiguous positional data and eliminating errors at transition points.

High Contact Reliability

Featuring gold-plated bifurcated contacts, these switches offer a low contact resistance of < 50mΩ and a mechanical life expectancy exceeding 1 million cycles, guaranteeing stable electrical performance.

Robust Environmental Sealing

Many models achieve an IP67 rating, providing complete protection against dust ingress and immersion in water up to 1 meter for 30 minutes, making them suitable for harsh industrial environments.

Wide Electrical Rating

Designed to handle significant loads, standard switches can manage currents up to 5A at 250V AC and have a dielectric strength of > 2,500V AC, ensuring safe operation under various power conditions.

Versatile Configuration Options

Available in single or multi-deck designs (up to 4 poles per deck), they support various codes like BCD, hexadecimal, or custom patterns, offering immense flexibility for complex circuit control.

Extended Operational Life

The precision-molded thermoplastic housing and stainless steel shaft contribute to an operational temperature range of -40°C to +85°C and exceptional resistance to mechanical wear and chemical corrosion.

Of course. Here are 5 application areas for a Coded Rotary Switch, formatted with text style codes.

1. Industrial Control Systems In harsh industrial environments, reliability is paramount. Coded rotary switches are used to select operational modes (e.g., Manual, Automatic, Jog) on Programmable Logic Controller (PLC) panels or to input setpoints. Their unique binary or Gray code output prevents ambiguous signals, ensuring a machine receives one clear command, which is critical for safety and process integrity.

2. Aerospace & Avionics Within aircraft cockpits, space is limited and error tolerance is zero. Coded switches are ideal for communication and navigation panels, allowing pilots to precisely select frequencies or input data. The digital output interfaces directly with avionic computers, reducing wiring complexity and weight compared to multi-pole switches, while providing absolute certainty in critical selections.

3. Medical Diagnostic Equipment High-end medical devices, such as ultrasound machines or blood analyzers, require precise calibration and mode selection. Coded rotary switches provide a robust, tactile interface for technicians to choose specific test protocols or adjust parameters. The digital encoding ensures there is no signal degradation over distance, guaranteeing the accuracy of sensitive measurements.

4. Professional Audio & Broadcasting In audio mixing consoles and broadcast routing systems, signal routing must be flawless. Coded switches are used for channel selection, input assignment, and level control. Their direct digital interface with microprocessors allows for recall of saved settings and automation, while the physical knob provides the immediate, hands-on control that audio engineers demand.

5. Test & Measurement Instruments Oscilloscopes, signal generators, and multimeters rely on coded rotary switches for primary function selection (e.g., Voltage, Current, Resistance). The switch's ability to generate a clean, bounce-free digital code allows the instrument's microcontroller to instantly reconfigure its internal circuitry, providing users with fast, accurate, and repeatable measurements.
