The **CK-16-R** typically refers to a specific series of **Rotary Switches** (often associated with brands like Alpha, Lorlin, or various electronic component manufacturers). These are mechanical components used to select different electrical paths by rotating a central shaft. --- ### 1. Technical Specifications Below are the general technical parameters for the CK-16-R series: | Parameter | Typical Value | | :--- | :--- | | **Switch Type** | Rotary | | **Number of Poles** | Usually 1 to 4 | | **Number of Positions** | Up to 12 (Adjustable) | | **Contact Rating** | 150mA at 250V AC/DC | | **Mounting Type** | Panel Mount / PCB Mount | | **Shaft Diameter** | 6mm or 6.35mm (1/4") | | **Body Material** | Polyamide (Nylon) or Zinc Alloy | --- ### 2. Core Electronic Parts & Construction The "CK" series is modular. The internal components work together to ensure precise indexing: * **The Rotor:** The central moving part connected to the shaft. It carries the common contact wiper. * **The Stator:** The stationary base containing the output terminals (pins). * **Indexing Mechanism:** A spring-loaded ball bearing or "click" plate that provides tactile feedback and ensures the switch stays in the selected position. * **Adjustable Stop Plate:** Most CK-16-R switches come with a metal washer with a "tooth." By placing this tooth in different holes around the shaft, you can limit the rotation (e.g., turning a 12-position switch into a 3-position switch). --- ### 3. Wiring Configurations The "16" in the part number often relates to the physical diameter or a specific pin layout. Common configurations include: 1. **1 Pole, 12 Positions:** 1 common pin, 12 output pins. 2. **2 Poles, 6 Positions:** 2 common pins, each switching between 6 outputs. 3. **3 Poles, 4 Positions:** 3 common pins, each switching between 4 outputs. 4. **4 Poles, 3 Positions:** 4 common pins, each switching between 3 outputs. ### 4. Common Applications * **Audio Equipment:** Selecting input sources (CD, Aux, Phono). * **Industrial Controls:** Mode selection (Manual, Auto, Off). * **Test Equipment:** Changing voltage ranges or measurement scales on a multimeter. ---
