The **M2TT-NE-R2** is a specific model of a miniature toggle switch, commonly utilized in industrial control panels, medical equipment, and telecommunications. This part belongs to a high-reliability series known for its durability and compact footprint. --- ### 1. Technical Specifications The following table highlights the core electronic and physical attributes of the M2TT-NE-R2: | Parameter | Specification | |:---|:---| | **Switch Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (Latching) | | **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 for 1 minute | | **Mechanical Life** | 100,000 cycles | | **Terminal Type** | PC Pin (Straight) | --- ### 2. Breakdown of Components The "Electronic Parts" of this switch consist of several integrated materials designed for high performance: * **Contact Mechanism:** Utilizes a "Butt Contact" mechanism. This design provides high reliability and a tactile "snap" feeling, ensuring the user knows the state has been toggled. * **Housing Material:** Typically made of Diallyl Phthalate (DAP) or high-grade resin. This provides excellent heat resistance during soldering and high dielectric insulation. * **Actuator:** The "NE" designation usually refers to a specific lever style (often a flatted or standard toggle) made of chrome-plated brass for corrosion resistance. * **Terminals:** Silver-plated or gold-over-silver contacts. Silver is used for high conductivity, while the plating prevents oxidation. --- ### 3. Circuit Application In a DPDT (Double Pole Double Throw) configuration, the M2TT-NE-R2 can control two independent circuits simultaneously. #### Connection Logic ```text Terminal 1 --- [Contact A] --- Terminal 2 (Common) --- [Contact B] --- Terminal 3 Terminal 4 --- [Contact C] --- Terminal 5 (Common) --- [Contact D] --- Terminal 6 ``` * In **Position 1**: Terminals 2 & 1 are connected; Terminals 5 & 4 are connected. * In **Position 2**: Terminals 2 & 3 are connected; Terminals 5 & 6 are connected. --- ### 4. Key Features for Engineers * **Anti-Jamming Design:** The internal construction prevents the toggle from being jammed by downward force on the actuator. * **High Torque Bushing:** The base of the toggle is reinforced to withstand high mechanical stress during installation into a chassis. * **Compact Size:** The "M2" series is specifically designed for high-density PCB mounting where space is a premium.
