The **M2TT-6E-R** is a specific electronic component, typically categorized as a **Miniature Toggle Switch** (often part of the M2 series by manufacturers like NKK Switches or similar industrial suppliers). This specific model is designed for PCB mounting and is known for its durability and small footprint. --- ### 1. General Specifications The "M2" series generally refers to process-sealed miniature toggles. Below are the typical technical characteristics: | Feature | Description | |:---|:---| | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON - ON | | **Mounting Type** | Through-hole (PCB Mount) | | **Actuator Style** | Standard Lever / Flatted Lever | | **Terminal Type** | Right Angle PC Terminals | --- ### 2. Breakdown of the Part Number (M2TT-6E-R) While naming conventions can vary slightly by manufacturer, the code generally breaks down as follows: * **M2**: Series identifier (Process Compatible Miniature Toggles). * **TT**: Often indicates the terminal spacing or specific sub-type (e.g., Twin-column or Tiny Toggle). * **6E**: Refers to the internal circuit and poles. "6" usually denotes DPDT, and "E" denotes the ON-ON logic. * **R**: Typically signifies the **Right Angle** terminal orientation, allowing the switch to be mounted perpendicular to the board. --- ### 3. Electrical & Mechanical Properties #### Electrical Ratings * **Logic Level:** Often used for low-voltage applications (0.4VA max @ 28V AC/DC). * **Contact Resistance:** Typically 20 milliohms maximum. * **Insulation Resistance:** 1,000 Megohms minimum @ 500V DC. #### Physical Construction * **Sealing:** These switches are usually **unsealed** or **process-sealed** (epoxy sealed base) to prevent contamination during soldering and cleaning. * **Contact Material:** Usually Gold-plated over Nickel or Silver-plated, depending on the specific sub-variant for signal integrity. * **Operating Temperature:** Generally rated for $-30^\circ\text{C}$ to $+85^\circ\text{C}$. --- ### 4. Typical Applications The M2TT-6E-R is commonly found in: 1. **Telecommunications:** Signal routing and mode selection. 2. **Instrumentation:** Power or function switching on handheld devices. 3. **Medical Equipment:** Control panels where space is limited. 4. **Audio/Visual:** Input/Output toggling on PCB-mounted interfaces. ---
