The **M2TS-11-R** is a specific electronic component, typically categorized as a **Surface Mount (SMD) Toggle Switch**. These components are widely used in telecommunications, instrumentation, and medical equipment where space is at a premium and automated assembly is required. --- ### 1. General Specifications The "M2TS" series generally follows industry standards for sub-miniature toggle switches. Below are the typical technical parameters: | Parameter | Specification | | :--- | :--- | | **Contact Configuration** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON - ON (2-position) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Terminal Type** | Right Angle (or Gull-wing depending on sub-suffix) | | **Contact Rating** | 0.4 VA max @ 20V AC/DC (Logic Level) | | **Electrical Life** | ~50,000 cycles | | **Operating Force** | 100 ~ 500 gf | --- ### 2. Key Electronic Features #### A. Logic Level Contacts Unlike power switches, the "R" in the suffix often denotes **Gold over Nickel** plating. This is critical for "logic level" applications where the voltage and current are so low that they cannot break through the oxide layer found on silver contacts. #### B. Environmental Sealing Most M2TS switches feature an internal O-ring or epoxy seal at the base. This provides: * **Process Compatibility:** Can withstand infrared (IR) reflow soldering. * **Washability:** Protection against cleaning solvents after the soldering process. #### C. Mechanical Actuation * **Toggle Lever:** Usually made of chrome-plated brass or high-temp thermoplastic. * **Housing:** Built from high-temperature UL94V-0 rated plastic to survive the heat of SMD ovens. --- ### 3. Pinout and Circuitry The M2TS-11-R is a **Single Pole Double Throw (SPDT)** device. It has three primary terminals: 1. **Terminal 1:** Fixed Contact A. 2. **Terminal 2:** Common (Center). 3. **Terminal 3:** Fixed Contact B. When the toggle is in Position 1, Terminal 2 is connected to Terminal 1. When flipped to Position 2, Terminal 2 connects to Terminal 3. --- ### 4. Typical Applications * **Handheld Devices:** Due to the small SMD footprint. * **Reset/Mode Selection:** Used as a physical configuration switch on PCBs. * **Medical Instrumentation:** High-reliability switching for diagnostic tools.
