The **LCS-15B-R** is a specific electronic component, most commonly identified as a **Limit Switch** or a **Miniature Snap Action Switch** (often part of the LCS series by manufacturers like Burgess or Saia-Burgess/Johnson Electric). Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Technical Specifications Table | Parameter | Details | | :--- | :--- | | **Switch Type** | Miniature Snap Action / Microswitch | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | Typically 5A to 15A (Depending on voltage) | | **Voltage Rating** | 125 / 250 VAC | | **Actuator Style** | Often a simulated roller or short lever (indicated by "B-R") | | **Termination** | Solder terminals or Quick Connect (0.110") | | **Operating Force** | Medium-High (Standard snap action) | --- ### 2. Key Electronic Features #### A. Contact Configuration (SPDT) The device typically features three terminals: * **COM (Common):** The input line. * **NC (Normally Closed):** Conducts electricity when the switch is at rest. * **NO (Normally Open):** Conducts electricity only when the actuator is pressed. #### B. Snap-Action Mechanism The "Snap-Action" means that the contact transfer happens at a specific speed regardless of how fast or slow the physical lever is pushed. This prevents "arcing" (sparks) between contacts, extending the electronic life of the part. #### C. Environmental Durability The LCS series is often rated for high-cycle life (frequently over 100,000 mechanical operations) and is designed to handle resistive loads in household appliances or industrial machinery. --- ### 3. Application Use Cases Due to its reliability, the LCS-15B-R is used in: 1. **Safety Interlocks:** Ensuring a microwave door or industrial guard is closed. 2. **Position Sensing:** Detecting the limit of travel in a motorized gate or 3D printer axis. 3. **Control Logic:** Acting as a physical trigger for a relay or PLC input. --- ### 4.
