The **M2RT-41-R2** is a specific part number typically associated with **M2R series toggle switches**, often manufactured by companies like NKK Switches. These are high-reliability, miniature toggle switches designed for PCB mounting. --- ### 1. Key Specifications & Components The following table summarizes the primary electronic and mechanical characteristics of the M2RT-41-R2: | Feature | Specification | | :--- | :--- | | **Circuit Type** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC / 4A @ 30V DC | | **Terminal Type** | Right Angle PC Terminals | | **Mounting Type** | Through-hole (PCB) | | **Actuator Type** | Round Toggle (Standard) | | **Contact Material** | Silver (Standard) or Gold (Option dependent) | --- ### 2. Internal Electronic Design The M2RT-41-R2 is built with several critical internal components that ensure electrical integrity: * **Bushing/Base:** Usually made of Diallyl Phthalate (DAP) or high-grade resin, providing high dielectric strength and heat resistance during soldering. * **Movable Contact:** A spring-loaded mechanism that "snaps" between positions to minimize arcing and ensure a firm electrical connection. * **Terminals:** These are epoxy sealed at the base to prevent flux, solvents, or contaminants from entering the switch housing during the manufacturing process. ### 3. Applications Due to its miniature size and DPDT configuration, this part is commonly used in: 1. **Industrial Controls:** Signal switching in control panels. 2. **Medical Equipment:** Reliable power or mode selection. 3. **Telecommunications:** Routing low-voltage signals on logic boards. 4. **Audio Gear:** Bypass or routing switches in pedals and consoles. ### 4. Mounting Diagram Logic In a DPDT "ON-ON" configuration, the pin layout typically follows this logic: ```text Position 1 (Left/Up): Pin 2 connected to Pin 1 Pin 5 connected to Pin 4 Position 2 (Right/Down): Pin 2 connected to Pin 3 Pin 5 connected to Pin 6 ``` ---
