Based on typical electronic component naming conventions, the **CK-10-R** generally refers to a specific series of **Rotary Switches**. These are mechanical components used to select different electrical paths by rotating a central shaft. --- ### 1. Technical Specifications The CK series is widely used in instrumentation, audio equipment, and industrial controls. Below are the common specifications for the CK-10-R variant: | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary Switch | | **Number of Poles** | 1 Pole | | **Number of Positions** | 10 Positions (Adjustable) | | **Switching Angle** | 30° per step | | **Contact Rating** | 150mA @ 250V AC/DC | | **Terminal Type** | Solder Lug or PC Terminals | | **Shaft Material** | Plastic or Metal (depends on sub-model) | | **Mounting Type** | Panel Mount | --- ### 2. Internal Construction The "CK" designation often follows the standard design for multi-wafer rotary switches: * **Rotor:** The central moving part connected to the shaft that makes contact with the terminals. * **Stator:** The fixed outer ring housing the output pins. * **Indexing Mechanism:** A spring-loaded ball or "clicker" that ensures the switch stays firmly in one of the 10 positions. * **Stop Plate:** Many "R" suffix models include a movable metal washer (stop ring) that allows the user to limit the rotation (e.g., changing it from a 10-position switch to a 4-position switch). --- ### 3. Pinout and Circuitry The CK-10-R is a **1-pole, 10-way (1P10T)** switch. * **Common Terminal (C):** Usually located in the center or offset from the outer ring. This is the input. * **Output Terminals (1-10):** Arranged in a circle. As you turn the knob, the Common terminal connects to each output sequentially. ### 4. Applications * **Voltage Selectors:** Choosing different power rails. * **Audio Equipment:** Selecting input sources (Phono, CD, Aux). * **Testing Equipment:** Changing ranges on a multimeter or oscilloscope. * **Fan Speed Controls:** Selecting between different resistance levels for motor speed. --- ### 5. Part Number Breakdown (Typical) | Code | Meaning | | :--- | :--- | | **CK** | Series Identifier (Compact Rotary) | | **10** | Maximum number of positions | | **R** | Often denotes "RoHS Compliant" or a specific "Round Shaft" configuration |
