The part number **M2TS-1D-R2** generally refers to a specific series of **Miniature Toggle Switches** often produced by manufacturers like **NKK Switches** or similar high-end electronic component providers. These are rugged, PCB-mounted components designed for logic-level or power switching in industrial and consumer electronics. --- ### 1. Component Breakdown The alphanumeric code identifies the physical and electrical characteristics of the switch: | Segment | Meaning | Description | | :--- | :--- | :--- | | **M2** | Series Prefix | Miniature process-sealed toggle switch series. | | **TS** | Type | Toggle Switch (Standard lever). | | **1D** | Circuit/Pole | Typically indicates **SPDT** (Single Pole Double Throw) with On-On functionality. | | **R2** | Terminals | Right-angle PCB mount (0.200" spacing or similar). | --- ### 2. Technical Specifications While specific datasheets may vary slightly by manufacturer, the M2TS series generally adheres to these standards: #### Electrical Characteristics * **Contact Rating:** * *Logic Level:* 0.4VA maximum @ 28V AC/DC. * *Power Level:* Up to 6A @ 125V AC (depending on contact material). * **Insulation Resistance:** 1,000 Megohms minimum @ 500V DC. * **Dielectric Strength:** 1,000V AC minimum between contacts for at least one minute. #### Mechanical & Environmental * **Actuator Style:** Standard round toggle lever. * **Sealing:** Often features an O-ring or epoxy seal at the base to prevent contamination during soldering and cleaning (Washable). * **Operating Temperature:** Typically ranges from **-30°C to +85°C**. * **Mechanical Life:** 100,000 operations minimum. --- ### 3. Pin Configuration (SPDT) For a **1D** (SPDT) configuration, the switch typically has three pins. In an "On-On" state: 1. **Pin 1 & 2:** Connected when the toggle is in one position. 2. **Pin 2 & 3:** Connected when the toggle is in the opposite position. 3. **Pin 2:** Common terminal. --- ### 4. Typical Applications * **Handheld Instruments:** Due to the small footprint and PCB mounting. * **Telecommunications:** Signal switching and routing. * **Medical Equipment:** Reliable user interfaces for diagnostic tools. * **Industrial Controls:** Mode selection or power resets on control boards.
