The part number **LP4-EE-1-R-G-B-R-Y** typically refers to a high-quality, multi-color illuminated push-button switch, often associated with manufacturers like **E-Switch** (LP4 series). This specific series is known for its modular design and extensive LED lighting options. --- ### 1. Breakdown of Part Number Components Based on the standard nomenclature for the LP4 series, here is the technical breakdown: | Component Code | Definition | Description | | :--- | :--- | :--- | | **LP4** | Series Name | Square/Rectangular Panel Mount Pushbutton Switch | | **EE** | Function | Latching (Push-on, Push-off) function | | **1** | Housing Style | Bezel/Housing type (usually black plastic) | | **R** | LED 1 Color | Red LED | | **G** | LED 2 Color | Green LED | | **B** | LED 3 Color | Blue LED | | **R** | LED 4 Color | Red LED (Secondary) | | **Y** | LED 5 / Cap | Yellow LED or Cap Color specification | --- ### 2. Key Technical Specifications These switches are designed for low-power signal switching and interface control. * **Circuit Configuration:** Typically DPDT (Double Pole, Double Throw). * **Contact Rating:** ~100mA @ 30VDC. * **Actuation Travel:** Full travel of approximately 3.0mm. * **Illumination:** Multiple LED chips integrated into a single switch body, allowing for status indication through different colors. * **Termination:** PCB Mount (Through-hole) or Solder Lug, depending on the specific pin layout. --- ### 3. Electronic Architecture The "R-G-B-R-Y" suffix indicates a complex illumination requirement. Internally, the switch contains multiple independent LED circuits: 1. **Independent Control:** Each LED color (Red, Green, Blue, etc.) usually has its own dedicated pins, allowing the user to trigger different colors based on system status. 2. **Common Anode/Cathode:** Depending on the internal wiring, the LEDs may share a common ground or common power pin to save space on the 10-pin or 12-pin footprint. 3. **Mechanical Action:** The "EE" designation means that when the button is pressed, it stays down (latched) until pressed again. --- ### 4. Typical Applications * **Audio/Visual Equipment:** Mixing consoles where different colors indicate different channel modes. * **Industrial Control:** Panels requiring multi-state feedback (e.g., Green = Go, Red = Stop, Yellow = Warning). * **Medical Instrumentation:** User interface buttons for diagnostic machines. * **Test & Measurement:** Mode selection buttons. ---
