The **LCS-02-R/E** is a specific model within a series of **Miniature Snap-Action Micro Switches**. These components are widely used in industrial control, automotive, and consumer electronics for sensing physical presence or position. Below is the detailed breakdown of its electronic specifications and characteristics. --- ### 1. Technical Specifications The "LCS" series is defined by its small form factor and high reliability. | Feature | Specification | | :--- | :--- | | **Switch Type** | Snap-Action Micro Switch | | **Current Rating** | 0.1A to 5A (Depending on specific load type) | | **Voltage Rating** | Typically 125V AC / 250V AC | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Operating Force** | Low to Medium Force (Standard for LCS series) | | **Mounting Type** | Through-hole / PCB Mount | ### 2. Part Number Breakdown (LCS-02-R/E) To understand the specific electronic parts, we decode the suffix: * **LCS**: Series Name (Subminiature Snap Switch). * **02**: Typically denotes the **Electrical Rating** (e.g., 0.1 Amp for gold-plated contacts or 5 Amp for silver contacts). * **R**: Indicates the **Actuator Type**. In this case, "R" usually refers to a **Roller Lever**. * **E**: Refers to the **Terminal Type** or **Operating Force**. In many configurations, "E" denotes a specific wire lead or a specific gram-force requirement for actuation. --- ### 3. Key Electronic Components & Materials The internal construction of the LCS-02-R/E consists of the following elements: 1. **Contacts**: * **Silver Alloy**: Used for higher current (Power) applications. * **Gold Plated**: Used for "Dry Circuit" (Low voltage/Low current) applications to prevent oxidation. 2. **Snap Mechanism**: A beryllium copper or stainless steel spring that ensures a rapid transfer of contacts regardless of the speed of the actuator. 3. **Housing**: Typically made of **PBT (Polybutylene Terephthalate)** or similar high-performance plastic with a UL94V-0 flammability rating. 4. **Terminals**: Brass with silver or tin plating for optimal solderability. ### 4. Application Use Cases * **Safety Interlocks**: Detecting if a door or panel is closed. * **Limit Sensing**: Detecting the end of travel in a mechanical arm or printer carriage. * **Control Panels**: Used as high-reliability buttons for industrial interfaces. --- ### 5. Wiring Diagram (SPDT) The device typically features three pins: ```text [ COM ] ---- Common Terminal [ NO ] ---- Normally Open (Closed when pressed) [ NC ] ---- Normally Closed (Open when pressed) ```
