The **M2TT-25-R** is a specific electronic component, typically categorized as a **Miniature Toggle Switch**. These components are widely used in industrial control panels, medical equipment, and telecommunications for manual circuit switching. Below is a detailed breakdown of its technical specifications and physical attributes. --- ### 1. Technical Specifications The M2TT-25-R is designed for low-to-medium power applications. Its performance is defined by its contact ratings and mechanical durability. | Parameter | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON - ON | | **Current Rating** | 6A @ 125VAC / 3A @ 250VAC / 4A @ 30VDC | | **Contact Resistance** | 10 mΩ Max | | **Insulation Resistance** | 1,000 MΩ Min @ 500VDC | | **Dielectric Strength** | 1,000 VAC for 1 minute | | **Operating Temperature** | -30°C to +85°C | --- ### 2. Key Physical Components The internal and external construction of the switch ensures long-term reliability. * **Actuator (The Lever):** Usually made of chrome-plated brass. It provides the physical interface for the user to flip the switch. * **Bushings:** The threaded part used for panel mounting. Standard sizing is usually 1/4-40 UNS or M6. * **Housing:** Typically made of Diallyl Phthalate (DAP), a high-strength plastic with excellent electrical insulation and heat resistance. * **Terminals:** Usually silver-plated or gold-plated brass to ensure low contact resistance and prevent oxidation. --- ### 3. Circuit Diagram Representation As a **DPDT** switch, it has 6 terminals. The internal switching logic functions as follows: ```text Terminal Layout: [ 1 ] [ 4 ] [ 2 ] [ 5 ] <-- Common Pins [ 3 ] [ 6 ] Operation: Position 1: Pin 2 connected to 1; Pin 5 connected to 4. Position 2: Pin 2 connected to 3; Pin 5 connected to 6. ``` --- ### 4. Applications The M2TT-25-R is frequently found in: 1. **Audio Equipment:** To toggle between different input sources or gain stages. 2. **Industrial Controls:** Used in control boxes for manual overrides. 3. **Test & Measurement:** Used in lab equipment to switch between different measurement modes. 4. **Networking:** Manual reset or configuration switches on rack-mounted hardware. ---
