The **M2SES-2BD-R/N** belongs to the **M2SES Series** of industrial control switches, specifically manufactured by manufacturers like **Autonics** or similar industrial automation brands. This model is a **22mm Selector Switch** designed for panel mounting in control circuits. --- ### 1. Technical Specifications The part number can be broken down to understand its electronic and physical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Series** | M2SES | Square/Round 22mm Industrial Selector Switch | | **Actuator Type** | Lever / Knob | Standard manual rotation | | **Positions** | 2-Position | Usually 90° angle between positions | | **Return Type** | Maintained (Stay-put) | Stays in the selected position until manually moved | | **Contact Block** | 1 NO + 1 NC | 1 Normally Open and 1 Normally Closed contact | | **Mounting Hole** | Ø22 mm | Standard industrial panel cutout size | | **Illumination** | Non-Illuminated | No internal LED/Lamp | --- ### 2. Electronic Contact Block Details The "R/N" suffix typically refers to the contact configuration and color (Red/Normal). The electronic reliability is defined by the following parameters: * **Rated Operational Voltage (Ue):** 110VAC, 220VAC, or 24VDC. * **Rated Operational Current (Ie):** Usually 5A to 10A depending on the AC/DC load type. * **Contact Resistance:** Max 50mΩ. * **Insulation Resistance:** 100MΩ at 500VDC. * **Dielectric Strength:** 2,500VAC for 1 minute. --- ### 3. Wiring Configuration The switch utilizes modular contact blocks. Below is a logic table for a standard 2-position selector: | Position | Contact 1 (NO) | Contact 2 (NC) | | :--- | :--- | :--- | | **Left (0)** | Open (Disconnected) | Closed (Connected) | | **Right (1)** | Closed (Connected) | Open (Disconnected) | --- ### 4. Application Examples This specific part is used in environments requiring manual intervention to toggle system states: * **Power On/Off:** Manual isolation of control power. * **Mode Selection:** Switching between "Manual" and "Auto" modes in a PLC system. * **Safety Interlocks:** Ensuring a specific circuit is broken before maintenance. ---
