The **M2TT-52-R2** is a high-performance, double-pole, double-throw (DPDT) electromechanical toggle switch often used in industrial and specialized electronic applications. It is part of the M2 series, known for its reliability and tactile feedback. --- ### 1. Technical Specifications Below are the primary electronic and physical parameters for the M2TT-52-R2: | Parameter | Specification | | :--- | :--- | | **Circuitry** | DPDT (Double Pole, Double Throw) | | **Switch Function** | ON - ON | | **Current Rating** | 6A @ 125VAC / 3A @ 250VAC | | **Contact Resistance** | 10 mΩ Max | | **Insulation Resistance** | 1,000 MΩ Min @ 500VDC | | **Dielectric Strength** | 1,000 VAC for 1 minute | | **Terminal Type** | PC Pin (Straight) | | **Actuator Style** | Standard Bat Lever | --- ### 2. Key Electronic Features * **Bifurcated Contacts:** The internal contact mechanism is designed to ensure low contact resistance and high reliability over time, even in low-current switching scenarios. * **Dual Pole Configuration:** Being a DPDT switch, it can control two separate circuits simultaneously or be used as a polarity-reversal switch for small DC motors. * **Mounting Design:** The "52" suffix generally denotes the specific terminal spacing and mounting hardware. The **PC Pin** termination allows it to be soldered directly onto a Printed Circuit Board (PCB). * **Durability:** It is rated for high mechanical life (typically over 50,000 cycles) and electrical life (over 25,000 cycles), making it suitable for professional equipment. --- ### 3. Connection Diagram (Standard DPDT) To integrate this into a circuit, understand the pinout logic: ```text Terminal Layout: [1] [4] <-- Pole A / Pole B [2] [5] <-- Common A / Common B [3] [6] <-- Pole A' / Pole B' Operation: - Position 1: Pin 2 connects to Pin 1; Pin 5 connects to Pin 4. - Position 2: Pin 2 connects to Pin 3; Pin 5 connects to Pin 6. ``` --- ### 4. Typical Applications * **Audio Equipment:** Signal routing and gain switching. * **Industrial Control:** Mode selection (Manual vs. Auto). * **Test & Measurement:** Powering on/off sensitive instrumentation. * **Telecommunications:** Network hardware configuration switches.
