The **LP4-EE-1-R-G-B-R-N** is a specific part number for a high-quality, illuminated pushbutton switch, typically manufactured by **E-Switch**. It is part of the LP4 series, known for its right-angle mounting and multiple LED illumination options. ### Product Specifications Breakdown The part number follows a specific nomenclature that defines its mechanical and electrical characteristics: | Feature | Code | Description | | :--- | :--- | :--- | | **Series** | LP4 | Square, right-angle illuminated pushbutton | | **Function** | EE | Latching (Push-on, push-off) | | **Circuit** | 1 | SPDT (Single Pole Double Throw) | | **LED 1 Color** | R | Red | | **LED 2 Color** | G | Green | | **LED 3 Color** | B | Blue (Full RGB capability) | | **Cap Color** | R | Red Cap | | **Legend** | N | No Legend (Plain surface) | --- ### Technical Components & Electronic Properties #### 1. Mechanical Switching * **Actuation Style:** Latching. This means the switch stays in the "down" position when pressed and requires a second press to return to the "up" position. * **Mounting:** Right-Angle PC Board Mount. The pins are bent at 90 degrees to allow the button to face the edge of the enclosure while the PCB sits flat. * **Travel:** Full travel is approximately 3.0mm. #### 2. Electrical Ratings * **Contact Rating:** Typically rated at **100mA @ 30VDC**. This switch is designed for signal-level switching, not for high-power AC loads. * **Contact Resistance:** 50mΩ Max (initial). * **Insulation Resistance:** 100MΩ Min at 500VDC. #### 3. RGB LED Integration This specific model features an **RGB LED configuration**. Unlike standard single-color switches, this part has internal LEDs for Red, Green, and Blue. * **Mixing:** By varying the voltage/current to the different LED pins, you can create secondary colors (Yellow, Cyan, Magenta, White). * **Common Anode/Cathode:** Typically, these LEDs share a common pin to save space on the PCB footprint. --- ### Typical Pinout Diagram (General) | Pin Number | Function | | :--- | :--- | | **1, 2, 3** | Switch Terminals (Common, NO, NC) | | **L1** | LED Red Cathode/Anode | | **L2** | LED Green Cathode/Anode | | **L3** | LED Blue Cathode/Anode | | **LC** | LED Common Pin | --- ### Common Applications * **Audio/Visual Equipment:** Used in mixing consoles or signal routers to indicate status. * **Test & Measurement:** Used for mode selection where color-coding helps identify the active state. * **Telecommunications:** Network hardware interfaces. * **Industrial Panels:** Compact control interfaces requiring multi-state visual feedback.
