The **M2RT-12-R** is a specific electronic component, typically categorized as a **Miniature Toggle Switch** or a specialized **Rotary Switch** depending on the manufacturer (most commonly associated with the NKK Switches M series or similar industrial series). Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Toggle Switch (Miniature) | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC | | **Contact Resistance** | 10 mΩ maximum | | **Insulation Resistance** | 1,000 MΩ minimum @ 500V DC | | **Dielectric Strength** | 1,000V AC minimum for 1 minute | | **Mechanical Life** | 100,000 Operations | --- ### 2. Key Electronic Parts & Construction The performance of the M2RT-12-R relies on several critical internal materials and design choices: * **Contacts (Silver Alloy):** The "R" in the suffix often denotes the contact material or specific plating. Silver-alloy contacts are used to handle higher current loads while maintaining low resistance. * **Actuator (Bushing/Toggle):** Usually made of brass with chrome plating for durability and environmental protection. * **Base (Diallyl Phthalate - DAP):** The housing is made of a high-heat resistant thermosetting plastic. This is critical for preventing the switch from melting during soldering. * **Terminal Seals:** Epoxy resin is used at the base of the pins to prevent solder flux and contaminants from entering the internal switching mechanism. --- ### 3. Circuit Application (DPDT) The **Double Pole Double Throw (DPDT)** configuration allows this part to control two separate circuits simultaneously. It has 6 terminals: 1. **Terminals 1 & 4:** Output A 2. **Terminals 2 & 5 (Common):** Input 3. **Terminals 3 & 6:** Output B In the **ON-ON** configuration, there is no "Center OFF" position. The switch is always directing current to one of the two output paths. --- ### 4. Installation and Mounting * **Mounting Type:** Panel Mount (Threaded Bushing). * **Termination:** Solder Lug (typical for the "R" series), allowing for direct wire attachment. * **Hardware:** Usually supplied with two hex nuts, one locking ring, and one internal tooth lock washer to ensure a secure vibration-proof fit. ---
