The **M2TT-2G-R2/Q** is a high-precision, miniature electromechanical component, typically identified as a **Toggle Switch** within the M2 series. These parts are widely used in industrial control panels, medical equipment, and telecommunications due to their high reliability and compact form factor. --- ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Switch Function** | DPDT (Double Pole Double Throw) | | **Actuator Type** | Standard Toggle (Bat style) | | **Terminal Type** | PC Pin (Right Angle) | | **Current Rating** | 6A @ 125VAC / 3A @ 250VAC | | **Contact Resistance** | 10 mΩ Max | | **Dielectric Strength** | 1,000V AC for 1 minute | | **Operating Temp** | -30°C to +85°C | --- ## Key Electronic Components & Materials ### 1. Contact Mechanism The "Q" suffix in the part number often denotes **Silver Contacts**. * **Material:** Silver alloy or silver plating over copper. * **Purpose:** Provides excellent conductivity and is ideal for power applications where minimal voltage drop is required. ### 2. Housing and Insulation * **Body:** High-temperature Diallyl Phthalate (DAP) or similar thermoset plastic. This ensures the switch body doesn't melt during soldering. * **Bushing:** Brass with nickel plating for corrosion resistance and mechanical strength. ### 3. Terminal Interface * **Mounting:** The **R2** designation typically refers to the **Right Angle PC Mount** configuration. This allows the switch to be mounted perpendicular to the Printed Circuit Board (PCB), saving vertical space. --- ## Application Use Cases 1. **Industrial Controls:** Used as a mode selector (e.g., Manual vs. Auto). 2. **Audio/Visual:** Signal routing in mixers or amplifiers due to low contact resistance. 3. **Medical Devices:** Reliable power on/off toggles for portable diagnostic tools. ---
