The part number **LP4-EE-1-R-W-B-R-G** refers to a high-quality, multi-color illuminated pushbutton switch, typically manufactured by **E-Switch** (LP4 series). This specific component is a panel-mount switch known for its square shape and multiple LED indicators. --- ### 1. Part Number Breakdown The nomenclature for this series defines the physical and electrical characteristics of the switch: | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | LP4 | Square Full-Illumination Pushbutton | | **Function** | EE | Latching (Push-on, push-off) | | **Circuit** | 1 | DPDT (Double Pole, Double Throw) | | **Cap Style** | R | Square Cap | | **Cap Color** | W | White (Translucent) | | **LED 1** | B | Blue | | **LED 2** | R | Red | | **LED 3** | G | Green | --- ### 2. Technical Specifications This component is designed for low-power signal switching and user interface feedback. * **Contact Rating:** Typically 100mA @ 30VDC. * **Circuitry:** **DPDT** (6 pins for the switch + additional pins for LEDs). This allows for controlling two separate circuits simultaneously. * **Operating Force:** 200 ± 50 grams. * **Travel:** 2.5mm total travel. * **Illumination:** RGB capability (Red, Green, and Blue LEDs included). Depending on how you wire the LED pins, you can achieve various colors or status indicators. * **Mounting:** Through-hole (PCB Mount). --- ### 3. Pin Configuration & Wiring Because this is a DPDT switch with three LEDs, the pinout is more complex than a standard toggle: 1. **Switch Terminals:** Two sets of Common (C), Normally Open (NO), and Normally Closed (NC) pins. 2. **LED Terminals:** Separate Anode/Cathode pins for the Blue, Red, and Green LED elements. * *Note:* You must use current-limiting resistors for the LEDs to prevent burnout. --- ### 4. Common Applications * **Audio/Visual Equipment:** Channel selection or "On-Air" indicators. * **Test & Measurement:** Mode selection in laboratory hardware. * **Control Panels:** Status indication (e.g., Green for OK, Red for Error, Blue for Standby). * **Kiosk/Vending:** User interface buttons requiring distinct visual feedback.
