The **M2TT-5E-R/N** is a specific model of a **Miniature Toggle Switch** manufactured by **NKK Switches**. These components are widely used in industrial control panels, medical equipment, and telecommunications for their reliability and tactile feedback. ### 1. Key Technical Specifications The following table highlights the primary electrical and mechanical characteristics of the M2TT-5E-R/N: | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON - ON (Maintained) | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC | | **Termination Style** | PC Pin (Right Angle) | | **Actuator Style** | Standard Bat Lever | | **Mounting Type** | Through-hole (PCB Mount) | --- ### 2. Electronic Parts Breakdown To understand the electronic and physical construction of this part, we can break it down into four main areas: #### A. Contact Mechanism (DPDT) The "DPDT" (Double Pole Double Throw) configuration means this switch has two separate input circuits (Poles) and can switch each between two output paths (Throws). It essentially functions like two SPDT switches operated by a single lever. #### B. Terminal Configuration (R/N) * **"R" suffix:** Indicates a **Right-Angle** mounting orientation. This means the lever protrudes horizontally while the pins are soldered vertically into a PCB. * **"N" suffix:** Generally denotes the contact material or a specific plating (often silver or gold over nickel), ensuring high conductivity and preventing oxidation. #### C. Housing and Insulation * **Case Material:** Typically made of Diallyl Phthalate (DAP) or a high-heat resistant resin. This provides high dielectric strength (typically 1,000V AC minimum between terminals). * **Internal Construction:** Uses a "sliding twin crossbar" or similar contact mechanism to ensure high reliability even in low-logic level applications. #### D. Environmental Protection The M2 series often features an internal O-ring or epoxy sealed terminals to prevent flux, solvents, and contaminants from entering the switch housing during the soldering process. --- ### 3. Connection Diagram (Internal Logic) The 6 pins on the bottom are typically arranged in two columns of three: ```text Column 1 (Pole 1) Column 2 (Pole 2) [ Pin 1 ] [ Pin 4 ] <-- Throw A [ Pin 2 ] [ Pin 5 ] <-- Common (Input) [ Pin 3 ] [ Pin 6 ] <-- Throw B ``` * In the **UP** position: Pin 2 connects to Pin 3; Pin 5 connects to Pin 6. * In the **DOWN** position: Pin 2 connects to Pin 1; Pin 5 connects to Pin 4.
