The **M2TT-13-R2** is a specific electronic component, typically categorized as a **Miniature Toggle Switch** designed for PCB (Printed Circuit Board) mounting. These components are widely used in industrial control panels, medical equipment, and telecommunications devices. --- ### 1. Key Technical Specifications Below is a summary of the typical electrical and mechanical properties for this series: | Property | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON - ON (Alternative) | | **Current Rating** | 6A @ 125VAC / 3A @ 250VAC | | **Contact Material** | Silver Plated (Standard) or Gold Plated | | **Mounting Type** | Through-hole (PCB Mount) | | **Terminal Type** | PC Terminals | --- ### 2. Physical Components & Materials The M2TT-13-R2 consists of several critical sub-parts that ensure its functionality: * **Actuator (The Toggle):** Usually made of chrome-plated brass or high-strength plastic. This is the part the user interacts with. * **Bushing:** The threaded or smooth neck of the switch. In the M2 series, this is often designed for compact spaces. * **Housing/Case:** Made of Diallyl Phthalate (DAP) or high-temperature UL94V-0 plastic to withstand soldering heat. * **Contacts:** The internal "blades" that complete the circuit. Silver is used for power applications, while gold is used for "dry circuits" (low voltage/low current) to prevent oxidation. --- ### 3. Circuit Diagram Representation In an electronic schematic, the DPDT configuration of the M2TT-13-R2 is represented as follows: ```text Terminal 1 (L1) --- [ Common 2 ] --- Terminal 3 (L1) Terminal 4 (L2) --- [ Common 5 ] --- Terminal 6 (L2) Pos 1: Connects 2 to 1 and 5 to 4 Pos 2: Connects 2 to 3 and 5 to 6 ``` --- ### 4. Common Applications * **Logic Switching:** Toggling between two different signal paths in a microcontroller circuit. * **Power Routing:** Switching between two different power sources (e.g., Battery vs. DC Wall Jack). * **User Interface:** Simple ON/OFF or Mode selection in handheld devices.
