The **LCS-0Z-R** belongs to the **LCS series** of subminiature snap-action switches manufactured by **C&K** (now part of Littelfuse). These components are widely used in industrial, consumer, and automotive applications where space is limited but high reliability is required. --- ### 1. Key Technical Specifications Below are the electrical and mechanical characteristics typical for the LCS-0Z-R model: | Characteristic | Specification | | :--- | :--- | | **Switch Type** | Subminiature Snap Action / Microswitch | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Current Rating** | 0.1A to 5A (depending on specific voltage/load) | | **Operating Force** | Typically 150g to 200g (varies by actuator) | | **Actuator Style** | Pin Plunger (Basic) | | **Termination Style** | Right Angle PCB Mount (Side Exit) | | **Mechanical Life** | Up to 1,000,000 cycles | | **Operating Temp** | -40°C to +120°C | --- ### 2. Physical Construction The "0Z-R" suffix specifically denotes the mechanical configuration of the pins and the actuator: * **Housing:** Compact thermoplastic (UL 94V-0 rated). * **Contacts:** Usually Silver (for power) or Gold-plated (for low-level logic switching). * **The "R" Suffix:** Usually indicates a **Right-hand side** terminal orientation or a specific PCB mounting direction, allowing the switch to be mounted flat against a board with the actuator facing outward. --- ### 3. Pin Configuration (SPDT) As a Single Pole Double Throw switch, it features three internal connection points: 1. **COM (Common):** The input terminal. 2. **NC (Normally Closed):** Connected to COM when the plunger is at rest. 3. **NO (Normally Open):** Connected to COM only when the plunger is depressed. --- ### 4. Typical Applications Because of its small footprint and "snap" feedback, the LCS-0Z-R is found in: * **Computer Peripherals:** Mouse buttons or joystick triggers. * **Industrial:** Limit switches for small motorized assemblies. * **Appliances:** Door interlocks or mode selection sensors. * **Automotive:** Interior lighting triggers or latch sensors. --- ### 5. Part Number Breakdown (LCS Series) To understand the exact variant, the code is generally decoded as follows: * **LCS:** Series Name. * **0:** Electrical Rating (e.g., 0.1A Gold contacts). * **Z:** Termination Type (PCB Mount/Solder). * **R:** Actuator or Mounting Orientation (Right Angle).
