The **M2TT-35-R** is a specific model of a **Miniature Toggle Switch**, typically manufactured by companies like **NKK Switches**. These components are designed for PCB (Printed Circuit Board) mounting and are known for their reliability in low-logic-level applications. --- ### 1. Technical Specifications The following table summarizes the key electrical and mechanical characteristics of the M2TT-35-R: | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON | | **Contact Rating** | 0.4VA Max @ 28V AC/DC Max (Logic Level) | | **Mounting Type** | Through-Hole, Right Angle | | **Actuator Style** | Standard Bat Lever | | **Terminal Type** | PC Pin (Gold Plated) | | **Operating Temp** | -30°C to +85°C | --- ### 2. Key Internal Components The "Electronic Parts" of this switch consist of several integrated materials that ensure electrical connectivity: * **Gold-Plated Contacts:** Unlike power switches that use silver, the M2TT-35-R uses gold plating. This is critical for **logic-level** signals because gold prevents oxidation, ensuring a stable connection even with very low voltages and currents. * **Carbon-Filled Polyamide Housing:** The outer shell is often made of high-performance plastic that provides high dielectric strength and heat resistance during soldering. * **Molded-in Terminals:** The terminals are epoxy-sealed or molded directly into the base. This prevents soldering flux, solvents, or contaminants from entering the internal switch mechanism. --- ### 3. Circuit Logic (DPDT) The DPDT configuration means the switch controls two separate circuits simultaneously. Each "pole" acts as a changeover switch. ```mermaid graph LR A[Common 1] --> B(Terminal 1) A --> C(Terminal 2) D[Common 2] --> E(Terminal 3) D --> F(Terminal 4) ``` --- ### 4. Common Applications Due to its **Right Angle** orientation and **Logic Level** rating, it is frequently used in: 1. **Handheld Devices:** Where space is limited and the switch must be accessible from the side of the enclosure. 2. **Medical Equipment:** For mode selection in diagnostic tools. 3. **Telecommunications:** For resetting or toggling internal logic states on a rack-mounted PCB. ---
