The **LCS-22112-R** is a specific surface-mount (SMD) sliding switch commonly used in consumer electronics, telecommunications, and industrial control interfaces. It belongs to the family of sub-miniature slide switches. --- ### 1. Technical Specifications Below are the primary electronic and mechanical characteristics of the LCS-22112-R. | Parameter | Specification | | :--- | :--- | | **Circuit Type** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (2-Position) | | **Current Rating** | 0.3A at 6V DC (Typical) | | **Contact Resistance** | ≤ 70mΩ | | **Insulation Resistance** | ≥ 100MΩ (at 500V DC) | | **Dielectric Strength** | 500V AC for 1 minute | | **Actuator Height** | ~2.0mm (standard) | | **Mounting Type** | Surface Mount (SMD/SMT) | --- ### 2. Physical Construction The part is designed for high-density PCB layouts where space is limited. * **Housing:** High-temperature thermoplastic (usually LCP or Nylon) capable of withstanding reflow soldering temperatures. * **Contacts:** Silver-plated or Gold-flashed copper alloy to ensure low contact resistance and prevent oxidation. * **Terminals:** Gull-wing or J-bend leads for surface mounting. * **Slider/Actuator:** Usually made of POM or similar friction-resistant plastic. --- ### 3. Pin Configuration (DPDT) As a **DPDT** switch, the LCS-22112-R controls two separate circuits simultaneously. Each "pole" has one common terminal and two throw terminals. ```text Terminal Layout (Simplified): [ 1 ] [ 2 ] [ 3 ] <-- Pole A [ 4 ] [ 5 ] [ 6 ] <-- Pole B Position 1: Pin 2 connects to 1; Pin 5 connects to 4. Position 2: Pin 2 connects to 3; Pin 5 connects to 6. ``` --- ### 4. Common Applications Due to its small footprint and reliable switching, it is frequently found in: 1. **Handheld Devices:** Power on/off switches or mode selectors. 2. **Audio Equipment:** Selecting between Mono/Stereo or Gain levels. 3. **Wearables:** Reset switches or user interface toggles. 4. **PC Peripherals:** Wireless mouse power switches or keyboard mode toggles. --- ### 5. Soldering Guidelines Since this is an SMD component, it is sensitive to heat and flux migration. * **Reflow Soldering:** Peak temperature should not exceed 260°C for 10 seconds. * **Flux Precaution:** Avoid using excessive flux as it can seep inside the switch body and cause contact failure.
