The **M2AS1-A314-R** is a specific electronic component, typically categorized as a **DIP (Dual In-line Package) Switch**. These components are widely used in industrial electronics, telecommunications, and consumer hardware to manually set hardware configurations. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this part series, here are the primary specifications: | Feature | Description | | :--- | :--- | | **Component Type** | DIP Switch / Slide Switch | | **Actuator Style** | Raised / Slide type | | **Number of Positions** | 4 Positions (Standard for the A314 variant) | | **Mounting Type** | Through-Hole (THT) | | **Pitch** | 2.54mm (0.1 inch) - Standard breadboard spacing | | **Contact Material** | Gold-plated (usually) for high reliability | | **Operating Temperature** | -20°C to +85°C (Approximate) | --- ### 2. Functional Details The "R" suffix usually denotes **RoHS Compliance** or a specific **Tape & Reel/Tube** packaging method. * **Switching Mechanism:** It functions as a simple SPST (Single Pole Single Throw) on/off switch for each of the 4 individual circuits. * **Electrical Rating:** Generally rated for low voltage/current (e.g., 25mA at 24VDC), making it suitable for logic-level signals rather than power switching. * **Durability:** Designed for high mechanical life, often exceeding 2,000 cycles. --- ### 3. Common Applications This part is typically found in the following scenarios: 1. **Address Setting:** Assigning unique IDs to devices on a communication bus (like RS-485 or CAN). 2. **Configuration:** Setting baud rates, operation modes, or enabling/disabling specific hardware features on a PCB. 3. **Security:** Manual override settings in alarm systems or industrial controllers. --- ### 4. Circuit Implementation To use this part in a digital circuit, it is usually paired with **pull-up or pull-down resistors** to ensure a stable logic state when the switch is open. ```cpp // Example: Reading a 4-position DIP switch on an Arduino int switchPins[] = {2, 3, 4, 5}; // Connected to M2AS1-A314-R pins void setup() { for(int i=0; i<4; i++) { pinMode(switchPins[i], INPUT_PULLUP); } } ```
