The **M2TT-80-R** is a specific model of a **Miniature Toggle Switch**, typically manufactured by companies like **NKK Switches**. These components are widely used in industrial control panels, medical equipment, and telecommunications for manual circuit switching. --- ### 1. Technical Specifications Below is a breakdown of the key electronic and physical characteristics of the M2TT-80-R: | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (Maintained) | | **Contact Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Mounting Type** | Through-hole, Right Angle PC Mount | | **Actuator Style** | Standard Bat Lever | | **Termination** | PC Pin | | **Operating Temperature** | -30°C to +85°C | --- ### 2. Electronic Component Breakdown #### A. DPDT Configuration (Double Pole Double Throw) The "Double Pole" means the switch controls two separate circuits simultaneously. The "Double Throw" means each pole can connect to one of two different output terminals. This is essentially two independent switches operated by a single lever. #### B. Logic Level Rating Unlike power switches, the M2TT-80-R is rated for **0.4VA maximum at 28V**. This indicates it is a **Logic Level** switch designed specifically for: * Interfacing with microcontrollers (Arduino, ESP32, etc.). * Low-power signal switching. * Environments where high reliability in low-voltage circuits is required (using gold-plated contacts to prevent oxidation). #### C. Right-Angle PC Mount The "R" in the suffix often denotes a **Right Angle** orientation. This means the switch sits horizontally on a Printed Circuit Board (PCB) while the toggle lever extends out the side. This is ideal for edge-mounting on devices where the user interacts with the side of the casing. --- ### 3. Pinout and Connection Logic The switch typically features 6 pins arranged in two rows: 1. **Common Pins (Middle):** Receive the input signal. 2. **Output Pins (Top/Bottom):** When the toggle is flipped, the Common pin connects to either the top or bottom pin, routing the signal accordingly. --- ### 4. Applications * **Handheld Instruments:** Due to the miniature size and right-angle mounting. * **Audio Equipment:** Switching between different signal paths or gain stages. * **Test & Measurement:** Mode selection in laboratory equipment.
