## Overview of M2RT-5A-R The **M2RT-5A-R** is a specific model of a **Miniature Toggle Switch**, typically manufactured by NKK Switches. It belongs to the M series, which is known for its high reliability and environmental resistance in industrial and electronic applications. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Contact Configuration** | DPDT (Double Pole Double Throw) | | **Switching Function** | ON-ON | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC / 4A @ 30V DC | | **Mounting Type** | Through-hole (PC Board Mounting) | | **Termination Style** | PC Terminals (Straight) | | **Actuator Style** | Standard Lever (Bushed) | | **Operating Temperature** | -30°C to +85°C | --- ### Key Electronic Components & Construction The M2RT-5A-R is composed of several high-quality materials designed to ensure electrical integrity: 1. **Contacts:** Usually made of silver (for power applications) or gold-over-silver (for logic-level applications). The "R" in the suffix often indicates compliance with RoHS standards. 2. **Housing/Case:** Constructed from Diallyl Phthalate (DAP) or similar high-heat resistant resin. This ensures the part can withstand soldering temperatures without warping. 3. **Internal Mechanism:** A spring-loaded "teeter-totter" mechanism ensures a "snap-action" feel, which minimizes electrical arcing and extends the life of the switch. 4. **Bushing:** Threaded or smooth brass (often nickel-plated) that provides structural support and allows for panel mounting if desired. --- ### Common Applications Due to its **DPDT ON-ON** configuration, this part is frequently used for: * **Signal Routing:** Switching between two different audio or data paths. * **Power Control:** Turning a device on/off or switching between two power sources. * **Industrial Controls:** Used in control panels where a physical, tactile feedback switch is required for safety and ease of use. * **Test Equipment:** Common in multimeters or signal generators for mode selection. ---
