The **WRS-6C2-R** is a specific model of a **Rotary Switch**, typically manufactured by companies like Alpha or similar electronic component providers. These switches are mechanical devices used to select between different electrical circuits by rotating a shaft. --- ### 1. Key Technical Specifications The model name "WRS-6C2-R" follows a specific nomenclature. Below is a breakdown of its primary electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary Switch | | **Poles** | 6 Poles | | **Positions** | 2 Positions | | **Contact Rating** | Usually 125V AC / 0.3A or 30V DC / 0.5A | | **Terminal Type** | PCB Mount (Pins) | | **Rotation** | 30-degree or 60-degree indexing (standard) | | **Shaft Material** | Usually Plastic or Metal (Ribbed or D-cut) | --- ### 2. Internal Configuration The "6C2" designation refers to the internal switching logic: * **6 Poles (6P):** There are 6 independent common input terminals. * **2 Positions (2T):** Each of those 6 inputs can be toggled between 2 different outputs. * **Total Pins:** Generally, this switch will have 18 pins (6 common pins + 12 output pins) plus potentially structural ground pins. ### 3. Electronic Functionality The WRS-6C2-R operates as a **Multi-pole Multi-throw (MPMT)** switch. When you turn the knob: 1. **Circuit Completion:** It simultaneously bridges 6 separate circuits. 2. **Selection:** It moves from "State A" to "State B" across all 6 channels at once. 3. **Break-Before-Make:** Most WRS series switches are "non-shorting," meaning the connection is broken on the first position before it is established on the second. --- ### 4. Common Applications Due to its high pole count (6), this switch is ideal for complex signal routing: * **Audio Equipment:** Selecting between different multi-channel inputs (e.g., switching balanced XLR signals). * **Industrial Controls:** Changing the mode of a machine that requires multiple sensors to be re-routed simultaneously. * **Test Equipment:** Switching between different measurement ranges or circuit paths in laboratory hardware. --- ### 5. Installation Note (Pinout) When looking at the bottom of the WRS-6C2-R, the pins are typically arranged in a circular pattern. * The **Inner Ring** usually contains the Common (C) pins. * The **Outer Ring** contains the Position (1-2) pins. ```markdown Note: Always verify the pinout with a multimeter in "continuity mode" before soldering, as manufacturers may update the internal wafer layout. ```
