The **LCS-03-R/E** is a specific model within a series of **Limit Switches** (often categorized as microswitches or snap-action switches). These are electromechanical devices used to detect the presence, position, or end-of-travel of an object. --- ### 1. General Specifications The "LCS" series generally refers to miniature snap-action switches. Below are the typical electronic characteristics associated with this part number: | Feature | Description | | :--- | :--- | | **Switch Type** | Miniature Snap-Action / Microswitch | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | Typically 0.1A to 5A (depending on voltage) | | **Actuator Type** | Lever / Roller Lever (indicated by suffix) | | **Termination** | Solder terminals or PCB pins | --- ### 2. Breakdown of the Model Code While naming conventions can vary slightly by manufacturer (such as *C&K Components* or *Honeywell*), the code usually breaks down as follows: * **LCS**: Series designation (Miniature Snap-Action). * **03**: Rating code (often indicates a specific amperage, e.g., 3 Amps or a specific gold-plating thickness for low-current applications). * **R**: Actuator Style (usually indicates a **Roller Lever**). * **E**: Operating Force (specifies the amount of pressure required to trigger the switch). --- ### 3. Electronic Components and Construction The internal mechanism consists of three primary electronic contact points: 1. **COM (Common):** The terminal where the input current enters. 2. **NC (Normally Closed):** The circuit is complete when the switch is in its resting state. 3. **NO (Normally Open):** The circuit is completed only when the lever is depressed. #### Materials * **Contacts:** Often silver alloy for standard power or gold-plated for low-level logic signals (to prevent oxidation). * **Housing:** Thermoplastic (often UL94V-0 rated) for high heat resistance and electrical insulation. --- ### 4. Common Applications Due to its small footprint and reliability, the LCS-03-R/E is used in: * **Industrial Automation:** Detecting the position of machine arms. * **Consumer Electronics:** Door interlocks for microwave ovens or printers. * **Automotive:** Detecting if a seatbelt is buckled or a door is latched. * **Vending Machines:** Detecting the passage of coins or product delivery. ---
