The **M2ADS-C22-R2** is a specific part number typically associated with an **Industrial Selector Switch** (often manufactured by brands like **Moujen**). It is a panel-mounted electromechanical component used to control the flow of electricity in industrial control circuits. --- ### 1. Technical Specifications The part number can be broken down into specific electrical and physical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Type** | Selector Switch | Rotating knob to switch between states. | | **Mounting Diameter** | 22mm | Standard industrial cutout size. | | **Contact Configuration** | 2NO (Normally Open) | Two sets of independent contacts. | | **Action Type** | Maintained / Stay-put | Stays in the selected position (doesn't spring back). | | **Handle Type** | Short Lever / Knob | Standard manual interface. | | **Voltage Rating** | 250V - 600V AC/DC | Varies based on insulation and contact load. | | **Current Rating** | 10A (Thermal) | Maximum continuous current the contacts can carry. | --- ### 2. Internal Electronic Components While the exterior is mechanical, the internal "electronic" or electrical parts are critical for operation: #### A. Contact Blocks * **Material:** Usually silver alloy to prevent oxidation and ensure high conductivity. * **Logic:** The "C22" indicates a specific contact arrangement. In a 2-position switch, turning the knob mechanically pushes a plunger to close the circuit. #### B. The Actuator * The rotating mechanism is designed for high mechanical durability (often rated for 500,000 to 1,000,000 cycles). * It utilizes a **cam-driven system** to convert rotational movement into linear movement for the contact blocks. #### C. Terminal Design * Uses **Screw Terminals** for secure wiring. * Designed to handle vibration in industrial environments to prevent electrical arcing or loose connections. --- ### 3. Application Circuit Example This switch is commonly used as a "Manual/Auto" toggle or an "On/Off" master switch for a control panel. ```yaml Circuit Example: [Power Supply] ---> [M2ADS-C22-R2 Terminal 1] [M2ADS-C22-R2 Terminal 2] ---> [Motor Starter Coil / PLC Input] ``` --- ### 4. Safety and Ratings * **IP Rating:** Typically **IP65**, meaning it is dust-tight and protected against water jets. * **Certifications:** Usually carries **UL, CE, and RoHS** certifications for international safety standards.
