The **M2SBS-211-R** is a specific part number belonging to a series of high-quality **miniature toggle switches**, typically manufactured by **Nidec Components (formerly Copal Electronics)**. These switches are widely used in industrial control panels, medical devices, and communication equipment due to their reliability and compact size. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical and mechanical characteristics. | Feature | Specification | | :--- | :--- | | **Switch Type** | Miniature Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole, Double Throw) | | **Switching Function** | ON - ON (Maintained) | | **Contact Rating** | 6A @ 125VAC / 3A @ 250VAC / 4A @ 30VDC | | **Contact Resistance** | 10 mΩ maximum | | **Dielectric Strength** | 1,500V AC for 1 minute | | **Insulation Resistance** | 1,000 MΩ minimum | | **Electrical Life** | 25,000 to 50,000 cycles (load dependent) | | **Operating Temp** | -20°C to +85°C | --- ### 2. Physical & Mechanical Properties The "M2" series is known for its robust construction and specific terminal types. * **Terminal Style:** The "R" suffix usually denotes **Right Angle PC terminals**. This means the switch is designed to be mounted on a Printed Circuit Board (PCB) horizontally. * **Actuator:** Standard toggle lever, typically made of chrome-plated brass. * **Bushing:** Threaded or plain, depending on the specific mounting bracket included (often 1/4-40 UNS or M6). * **Sealing:** These units often feature an internal O-ring or epoxy-sealed base to prevent flux contamination during soldering. --- ### 3. Pinout and Circuit Logic (DPDT) Since this is a **DPDT** switch with an **ON-ON** configuration, it has 6 terminals. ```text [ Terminal 1 ] [ Terminal 4 ] [ Terminal 2 ] [ Terminal 5 ] <-- Common Pins [ Terminal 3 ] [ Terminal 6 ] Position 1: 2-1 connected, 5-4 connected. Position 2: 2-3 connected, 5-6 connected. ``` --- ### 4. Key Applications * **Industrial Automation:** Selecting between two modes of operation or two different power sources. * **Test Equipment:** Signal routing in oscilloscopes or multimeters. * **Audio Equipment:** Phase reversal or input switching. * **Networking:** Manual hardware resets or configuration overrides. ---
