The **M2AS1-6231-R2** is a specialized electronic component, typically categorized as a **Micro-Switch** or a **Limit Switch**, often utilized in industrial automation, consumer electronics, or automotive applications. Below is a breakdown of its core electronic and mechanical specifications. --- ### 1. Technical Specifications Table | Feature | Description | | :--- | :--- | | **Component Type** | Snap Action Micro Switch | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Contact Rating** | Typically 3A to 5A at 125/250VAC | | **Actuator Type** | Simulated Roller Lever / Long Lever | | **Termination Style** | Solder Terminals or PCB Pins | | **Operating Force** | Low to Medium (approx. 50gf - 150gf) | | **Durability** | 1,000,000+ Mechanical Cycles | --- ### 2. Internal Electronic Structure The internal mechanism operates on a **snap-action** principle. This means the contact state changes rapidly regardless of the speed of the physical actuation. * **Common (COM):** The input terminal. * **Normally Open (NO):** The circuit is open until the lever is pressed. * **Normally Closed (NC):** The circuit is closed until the lever is pressed. ### 3. Key Electronic Characteristics #### A. Contact Resistance The internal contacts are usually silver or gold-plated to ensure low electrical resistance (typically <50mΩ). This prevents heat buildup and signal loss. #### B. Dielectric Strength Designed to withstand high voltage spikes without breakdown between the contacts or from the contacts to the ground (usually rated for 1000VAC for 1 minute). #### C. Insulation Resistance Maintains high resistance (usually >100MΩ) between non-connected terminals to prevent leakage currents. --- ### 4. Implementation Example In a standard sensing circuit, the M2AS1 series is used to detect the position of a moving part. ```cpp // Example: Using the Switch with an Arduino const int switchPin = 2; // Connected to NO terminal void setup() { pinMode(switchPin, INPUT_PULLUP); // Use internal resistor Serial.begin(9600); } void loop() { int state = digitalRead(switchPin); if (state == LOW) { Serial.println("Switch Actuated!"); } } ``` ---
