The **M2RT-3A-R/BL** is a specific model of a **Miniature Toggle Switch**, typically manufactured by companies like NKK Switches or similar industrial component providers. Below is a breakdown of its electronic and physical specifications. --- ### 1. Component Identification This part belongs to the **M2 series**, known for being process-sealed, subminiature toggle switches designed for PC board mounting. | Feature | Specification | | :--- | :--- | | **Series** | M2 Series (Process Sealed) | | **Circuit** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-OFF-ON (Three-position) | | **Actuator Style** | Standard Lever (3A denotes short lever) | | **Terminal Type** | Right Angle PC Mount | | **Color/Material** | Black (BL suffix often refers to the bushing or lever color) | --- ### 2. Electrical Characteristics These parameters define the limits within which the switch can operate safely. * **Contact Rating:** Generally rated for low logic level applications. * *Max:* 0.4VA max @ 28V AC/DC. * **Contact Resistance:** 20 milliohms maximum. * **Insulation Resistance:** 1,000 megohms minimum @ 500V DC. * **Dielectric Strength:** 500V AC minimum for at least one minute. * **Mechanical Life:** Typically 100,000 operations. --- ### 3. Key Physical Features * **Process Sealed:** The "M2" designation usually implies the switch is sealed with an O-ring and epoxy. This allows the component to undergo automated wave soldering and cleaning (washing) without internal contamination. * **Right Angle Mounting:** The "R" in the part number indicates a right-angle orientation, meaning the toggle moves parallel to the PCB surface while the pins are soldered vertically into the board. * **Double Pole Double Throw (DPDT):** It controls two separate circuits, allowing for complex switching logic (e.g., reversing motor direction or switching between two different signal paths). --- ### 4. Circuit Diagram Representation The **ON-OFF-ON** configuration works as follows: ```text Position 1 (Left): Pins 2-1 and 5-4 connected Position 2 (Center): All pins disconnected (OFF) Position 3 (Right): Pins 2-3 and 5-6 connected ``` ---
