The **M2TT-5A-R2/N** belongs to a specific category of miniature, high-reliability toggle switches, often utilized in industrial control panels, medical equipment, and telecommunications. Below is a detailed breakdown of its electronic and physical characteristics. --- ### 1. Technical Specifications The "M2" series generally identifies the miniature toggle line, while the suffixes define the specific electrical behavior and terminal plating. | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switching Function** | ON - ON | | **Current Rating** | 6A @ 125VAC / 3A @ 250VAC | | **Terminal Type** | Solder Lug / PC Terminals (depending on sub-variant) | | **Contact Material** | Silver (R2 indicates specific contact plating) | | **Actuator Style** | Standard Bat Lever | --- ### 2. Component Breakdown #### A. Contact Configuration (DPDT) The **Double Pole Double Throw** setup means this switch can control two separate circuits simultaneously. It has six terminals: * **Two Common Pins:** The input source. * **Four Output Pins:** Two for the "Up" position and two for the "Down" position. * **ON-ON Function:** Unlike a momentary switch, this is a maintained switch. It stays in the position it is moved to. #### B. The "R2" Designation In electronic parts coding for this series, the **R2** usually refers to the **Contact Material and Rating**. * **Silver Contacts:** High conductivity, ideal for power applications (up to 6 Amps). * **Mechanical Life:** Typically rated for 50,000 to 100,000 cycles. #### C. Environmental Rating (/N) The **/N** suffix often relates to the finish or specific environmental compliance: * **Bushings:** Usually threaded for panel mounting. * **Nitrogen/Sealing:** In some manufacturer contexts, this indicates a specific sealing process or a "non-shorting" (break-before-make) contact mechanism. --- ### 3. Application Use Cases Due to its miniature form factor and high pole count (DPDT), it is commonly used for: 1. **Polarity Reversal:** Wiring a DC motor to run forward or backward. 2. **Signal Routing:** Switching an audio or data signal between two different outputs. 3. **Power Redundancy:** Switching a device between a Battery source and an AC Adapter source. --- ### 4.
