The **M2UDS-14-R/N** is a specific electronic component typically categorized as a **DIP (Dual In-line Package) Switch**, often used for configuration settings on printed circuit boards (PCBs). --- ### 1. Technical Specifications The part number breakdown generally refers to its mechanical and electrical characteristics: | Feature | Specification | | :--- | :--- | | **Part Type** | DIP Switch (Standard Slide/Piano Type) | | **Number of Positions** | 14 Positions (Individual switches) | | **Mounting Type** | Through-Hole (THT) | | **Pitch** | 2.54mm (0.1 inch) - Standard breadboard spacing | | **Actuator Style** | Raised (R) or Recessed | | **Contact Rating** | Usually 25mA at 24VDC (Switching) | | **Insulation Resistance** | 100MΩ min. at 500VDC | --- ### 2. Physical Construction The "14" in the part number indicates it has **14 individual poles** (on/off toggles). * **Housing:** Typically made of high-temperature PBT or UL94V-0 rated plastic. * **Contacts:** Gold-plated or tin-plated copper alloy to ensure low contact resistance and prevent oxidation. * **Terminal Layout:** Dual In-line (2 rows of 14 pins), totaling 28 pins. --- ### 3. Common Applications This component is used where semi-permanent settings are required without needing a microcontroller interface for every change: * **Address Setting:** Setting unique IDs for devices on a communication bus (e.g., RS-485 or DMX). * **Configuration:** Selecting baud rates, operating modes, or frequency bands. * **Security:** Mechanical coding for garage door openers or older remote controls. * **Prototyping:** Hard-wiring logic levels (High/Low) during circuit testing. --- ### 4. Circuit Diagram Representation In a schematic, each of the 14 switches is represented as a simple SPST (Single Pole Single Throw) switch. ```text Pin 1 o---/ ---o Pin 28 Pin 2 o---/ ---o Pin 27 ...
