Based on the part number provided, this appears to be a specific configuration of a **rotary switch** or **selector switch**, typically used in industrial control panels or automation systems. While specific data sheets for proprietary part numbers can vary by manufacturer (often associated with brands like **IDEC**, **Schneider**, or **ABB**), the code structure provides significant information about its electronic and physical components. ### 1. Breakdown of the Component Code | Segment | Component Type | Description | | :--- | :--- | :--- | | **M2** | Series/Size | Usually indicates a **22mm** diameter mounting hole standard. | | **PHS** | Actuator Type | **P**ush/Selector **H**andle **S**witch. This often implies a spring-return or maintained selector knob. | | **2W** | Positions | Indicates a **2-Way** (2-position) operation (e.g., 90° or 45° throw). | | **C1** | Contact Block | Indicates **1 Normally Closed (NC)** contact block. | | **R2** | Color/Variation | Often refers to a **Red** color actuator or a specific revision of the contact holder. | --- ### 2. Key Electronic Specifications Typical specifications for industrial switches in this category include: * **Insulation Voltage (Ui):** Usually rated up to 600V. * **Thermal Current (Ith):** Typically 10A. * **Contact Resistance:** $\le 50m\Omega$. * **Mechanical Life:** Generally rated for 500,000 to 1,000,000 cycles. * **Operating Temperature:** Standard range is $-25°C$ to $+70°C$. ### 3. Connection and Wiring The device utilizes modular contact blocks. Below is the standard wiring logic for the **C1 (NC)** configuration: ```text Terminal 1 (L1) ---- [Normally Closed Switch] ---- Terminal 2 (Out) (Current flows when the switch is in the 'Rest' position) ``` --- ### 4. Physical Characteristics 1. **Mounting:** Designed for a standard 22.5mm cutout in a control box or panel. 2. **Ingress Protection:** Usually rated **IP65** (Dust-tight and protected against water jets). 3. **Material:** The body is typically made of high-impact flame-retardant plastic or chrome-plated metal.
