The **M2TT-N4-R** is a specific model of an industrial control switch, typically categorized as a **Miniature Toggle Switch** or part of a push-button/indicator series depending on the specific manufacturer (commonly associated with brands like Omron or IDEC in industrial automation). Below is the technical breakdown of its electronic and mechanical parts. ### 1. Technical Specifications The electrical characteristics define how the part handles voltage and current within a circuit. | Feature | Description | | :--- | :--- | | **Contact Form** | DPDT (Double Pole Double Throw) | | **Switching Action** | ON-ON (Maintained) | | **Current Rating** | Typically 6A at 125VAC / 3A at 250VAC | | **Contact Resistance** | 10 mΩ max (initial) | | **Insulation Resistance** | 1,000 MΩ min (at 500 VDC) | | **Dielectric Strength** | 1,500 VAC, 50/60 Hz for 1 minute | --- ### 2. Physical & Electronic Components The device is composed of several critical internal and external parts: #### A. Contact Mechanism (Internal) * **Movable Contacts:** Usually made of silver or silver-alloy. These physically move to bridge the gap between terminals. * **Stationary Terminals:** The physical pins protruding from the bottom. The "R" in the suffix often denotes **Right Angle** PC terminals for PCB mounting. #### B. The Housing (Body) * **Material:** High-grade Diallyl Phthalate (DAP) or similar thermosetting plastic. This provides high heat resistance and electrical insulation. * **Sealing:** Often includes an internal O-ring or epoxy seal at the base to prevent solder flux or contaminants from entering the contact area. #### C. Actuator (The Toggle/Lever) * **N4 Suffix:** Usually refers to the specific lever style (e.g., a standard bat-style or short lever). * **Mechanical Life:** Designed for approximately 50,000 to 100,000 operations. --- ### 3. Connection Layout As a **DPDT** switch, it features 6 terminals. This allows the switch to control two separate circuits simultaneously. ```mermaid graph TD A[Terminal 1] --- B[Common 1] B --- C[Terminal 2] D[Terminal 3] --- E[Common 2] E --- F[Terminal 4] ``` --- ### 4. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature generally follows this logic: * **M2TT:** Series designation (Miniature Toggle). * **N4:** Actuator/Lever type (Length and Shape). * **R:** Terminal type (Right-angle PCB mount).
