The **MS-10-R** is typically identified as a **high-precision, compact micro-switch** (often from manufacturers like Copal Electronics or similar industrial suppliers) or a specific **miniature sensor/relay** component. Below is an overview of the electronic specifications, construction, and functionality commonly associated with this part series. --- ## 1. Technical Specifications Most parts in the MS-10 series follow these standard electrical parameters: | Feature | Description | | :--- | :--- | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Switching Capacity** | Typically 0.1A to 10A (Depending on voltage) | | **Rated Voltage** | 125V AC / 250V AC or 30V DC | | **Contact Resistance** | < 50 mΩ (initial) | | **Insulation Resistance** | > 100 MΩ (at 500V DC) | | **Operating Force** | Light force (often 0.49N to 1.47N) | --- ## 2. Key Electronic Components & Materials The reliability of the MS-10-R comes from its internal material composition: * **Contacts:** Usually made of **Silver Alloy** or **Gold-plated Silver** (the "R" suffix often denotes RoHS compliance or specific contact plating). * **Actuator:** A miniature lever or plunger that triggers the internal snap-action mechanism. * **Housing:** High-grade PBT (Polybutylene terephthalate) or PPS (Polyphenylene sulfide) for heat resistance and electrical insulation. * **Terminals:** Solder terminals, PCB terminals, or Quick-connect tabs. --- ## 3. Circuit Configuration The MS-10-R operates as a basic switch. Below is the typical pinout logic: ```mermaid graph LR A[COM - Common] --- B[NC - Normally Closed] A --- C[NO - Normally Open] ``` ### Operation Logic: 1. **Rest State:** The circuit is closed between **COM** and **NC**. 2. **Actuated State:** When the button/lever is pressed, the internal spring snaps, opening COM-NC and closing the circuit between **COM** and **NO**. --- ## 4. Typical Applications Due to its small footprint and high reliability, it is used in: * **Industrial Automation:** Limit switches for moving parts. * **Consumer Electronics:** Door detection in microwaves or printers. * **Automotive:** Detecting gear positions or seatbelt latching. * **Medical Devices:** Pressure or position sensing in pumps. ---
