### Overview of the M2TT-52-R2/N The **M2TT-52-R2/N** is a specific variant of a miniature toggle switch, typically manufactured by **NKK Switches**. These components are widely used in industrial controls, medical equipment, and communication devices due to their reliability and compact form factor. --- ### Technical Specifications The following table outlines the primary electrical and physical characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole, Double Throw) | | **Switch Function** | ON - ON (Maintained) | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC / 4A @ 30V DC | | **Mounting Type** | Through-Hole (PCB Mount) | | **Termination Style** | PC Pins (Straight) | | **Actuator Style** | Standard Bat Lever | | **Operating Temperature** | -30°C to +85°C | --- ### Key Electronic Features #### 1. DPDT Circuitry As a **Double Pole, Double Throw** switch, it controls two separate circuits simultaneously. Each "pole" has a common terminal that can be switched between two different output paths. #### 2. Contact Material and Reliability The "/N" or "R2" suffixes often denote specific contact plating or environmental ratings. * **Contacts:** Typically silver-plated or gold-over-silver. Silver is excellent for power applications, while gold is preferred for "dry circuits" (low voltage/low current) to prevent oxidation. * **Life Expectancy:** Usually rated for 50,000 to 100,000 mechanical cycles. #### 3. Physical Construction * **Bushing:** Features a threaded or non-threaded neck for mounting. * **Sealing:** These models often feature internal O-rings or epoxy-sealed terminals to prevent solder flux or contaminants from entering the switch mechanism during the manufacturing process. --- ### Typical Applications * **Test & Measurement:** Routing signals between different sensors. * **Audio Equipment:** Toggling between different input sources or gain stages. * **Industrial Panels:** Manual override controls for automated systems. ---
