The **LP4-EE-1-R-G-B-R-G** is a high-quality, illuminated push-button switch part number, typically associated with manufacturers like **E-Switch** (LP4 series). This specific model is a right-angle, through-hole mounted switch featuring full RGB LED integration. ### 1. Part Number Breakdown The alphanumeric code describes the mechanical and electrical characteristics of the switch: | Segment | Meaning | Description | | :--- | :--- | :--- | | **LP4** | Series | Large square/rectangular illuminated pushbutton series. | | **EE** | Function | DPDT (Double Pole Double Throw), Latching (Push-on, Push-off). | | **1** | Actuator Style | Square button profile. | | **R-G-B** | LED Colors | Red, Green, and Blue LEDs included (RGB). | | **R-G** | Housing/Cap | Indicates the bezel or cap color finishes (typically Transparent/Grey). | --- ### 2. Electrical Specifications This component is designed for signal-level switching rather than high-power AC applications. * **Contact Rating:** 100mA @ 30VDC. * **Contact Resistance:** 50mΩ Max (Initial). * **Insulation Resistance:** 100MΩ Min @ 500VDC. * **Dielectric Strength:** 500VAC for 1 minute. * **Operating Life:** 50,000 cycles (minimum). --- ### 3. LED Characteristics (RGB) The "RGB" designation means the switch contains three separate LED dies. By controlling the voltage to each pin, the user can create various colors. | Color | Typical Forward Voltage ($V_f$) | Max Forward Current ($I_f$) | | :--- | :--- | :--- | | **Red** | 1.95V | 20mA | | **Green** | 3.3V | 20mA | | **Blue** | 3.3V | 20mA | --- ### 4. Physical & Mounting Features * **Mounting Type:** **Right Angle, Through-Hole (PC Mount)**. The pins are bent at a 90-degree angle so the button faces the edge of the PCB. * **Circuitry:** **DPDT (Double Pole Double Throw)**. This allows the switch to control two separate circuits simultaneously with two positions each. * **Travel:** Full travel is approximately 3.0mm; Lock travel is 2.5mm. * **Actuation Force:** Approximately 300 gf (grams-force). --- ### 5. Common Applications Due to its aesthetic appeal and RGB feedback, this part is commonly found in: 1. **Audio/Video Equipment:** Mixing consoles and signal processors. 2. **Test & Measurement:** Front panel controls for lab instruments. 3. **Industrial Controls:** Status indicators where different colors represent different machine states (e.g., Red = Error, Green = Running). 4. **Computer Peripherals:** Custom macro pads or server rack power buttons.
