Based on the technical nomenclature provided, the **M2TT-60-R2/BN** (often stylized with a slash or dash depending on the manufacturer) refers to a specialized **M2 series Miniature Toggle Switch**, typically produced by manufacturers like **NKK Switches**. --- ## Technical Specifications Overview The following table breaks down the primary electrical and mechanical characteristics of this component series: | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON - ON (Maintained) | | **Current Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Contact Material** | Gold Plated (for low-level switching) | | **Mounting Type** | Through-hole PC Mount (Right Angle) | | **Actuator Style** | Standard Bat Lever | --- ## Detailed Breakdown of Parts ### 1. The Contacts (Gold Plated) The "R2" designation often implies the use of gold-over-nickel plating. Unlike silver contacts, gold does not oxidize, making it ideal for **logic-level circuits** where the voltage and current are too low to "arc" through oxidation. ### 2. Terminal Configuration (Right Angle) The **BN** suffix usually indicates the terminal spacing and orientation. In this specific model: * **Right Angle Mount:** The toggle sticks out horizontally from the PCB rather than vertically. * **Bracketed:** It likely includes a support bracket to ensure mechanical stability when the user flips the switch, preventing the solder joints from cracking. ### 3. Bushing and Actuator * **Bushing:** Usually threaded or plain (6mm diameter is standard for the M2 series). * **Seal:** Many versions of the M2 series feature an internal o-ring or epoxy seal at the base to prevent soldering flux or contaminants from entering the contact chamber. --- ## Component Application Because this part is rated for **0.4VA**, it is **not** designed to switch power loads (like motors or bright lamps). Instead, it is used for: 1. **Signal Routing:** Directing data signals between different paths on a PCB. 2. **User Interfaces:** Serving as a "Mode Select" or "On/Off" toggle for battery-operated handheld devices. 3. **Industrial Controls:** Integrated into control panels where a compact, reliable mechanical interface is required. --- ## Typical Pinout Logic ```text [Terminal 1] -- [Terminal 2 (Common)] -- [Terminal 3] [Terminal 4] -- [Terminal 5 (Common)] -- [Terminal 6] ``` *When the toggle is in Position A, Terminals 2-3 and 5-6 are connected. When flipped to Position B, Terminals 2-1 and 5-4 are connected.*
