The **M22-WLKV-R** is a high-quality industrial pilot device from Eaton’s Moeller series (M22 Global line). It is a **Non-Illuminated, 2-Position Rotary Selector Switch** designed for manual control of electrical circuits. --- ### 1. Technical Specifications The following table outlines the core electronic and mechanical characteristics of the M22-WLKV-R: | Feature | Specification | | :--- | :--- | | **Series** | M22 (RMQ-Titan) | | **Function** | Selector Switch (Rotary) | | **Positions** | 2-Position (V-Shape) | | **Actuator Type** | Maintained (Stays in position) | | **Illumination** | Non-Illuminated (Thumb-grip style) | | **Bezel Material** | Titanium (Silver colored plastic) | | **Color** | Black (Actuator) | | **Degree of Protection** | IP66 (NEMA 4X, 13) | | **Standard Hole Diameter** | 22.5 mm | --- ### 2. Component Structure The M22 system is modular. To make the **M22-WLKV-R** functional in an electrical circuit, you typically need the following three parts: 1. **The Operator (M22-WLKV-R):** The front-facing mechanical knob that the user turns. 2. **The Fixing Adapter (M22-A):** The mounting bracket that clips onto the back of the operator to hold contact blocks. 3. **Contact Blocks (M22-K series):** The actual electrical switching components. * **M22-K10:** Normally Open (NO) * **M22-K01:** Normally Closed (NC) --- ### 3. Electrical Operation The "Electronic" part of this device relies on how it interacts with the contact blocks attached to it. * **Switching Logic:** In a 2-position maintained switch, the knob can be turned to a specific angle (usually 60°). It stays in that position until manually turned back. * **Circuit Control:** By turning the knob, internal cams press against the plungers of the attached **M22-K** contact blocks, either closing or opening the electrical path. * **Applications:** Commonly used for "Hand/Auto" selection, "Start/Stop" functions, or toggling between two different power sources in a control panel. ### 4. Wiring Diagram Example When wiring the contact blocks associated with this switch, a basic setup looks like this: ```markdown [Power Source L1] ---- [M22-K10 (NO Block Terminals 3-4)] ---- [Motor Starter/Load] ---- [Neutral] ``` * **Position 0 (Left):** Contacts are Open (Circuit is OFF). * **Position 1 (Right):** Contacts are Closed (Circuit is ON). ---
