The part number **LP4-EE-1-R-W-C-R-B** refers to a high-quality, illuminated pushbutton switch, typically manufactured by **E-Switch** as part of their LP4 series. These switches are commonly used in audio/video equipment, instrumentation, and telecommunications. --- ### 1. Part Number Breakdown (Specifications) The alphanumeric code describes the mechanical and electrical characteristics of the switch: | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | LP4 | Low profile, illuminated pushbutton switch | | **Function** | EE | Latching (Push-on, Push-off) | | **Circuit** | 1 | DPDT (Double Pole, Double Throw) | | **Actuator** | R | Round Button | | **Housing** | W | White Housing | | **Illumination** | C | Full Face Illumination | | **LED 1 Color** | R | Red LED | | **LED 2 Color** | B | Blue LED | --- ### 2. Key Electronic Features #### A. Circuitry: DPDT (Double Pole, Double Throw) This switch controls two separate circuits simultaneously. Each "pole" can switch between two different output paths, making it ideal for complex signal routing or controlling two different power states at once. #### B. Switching Action: Latching (EE) Unlike a momentary switch (which springs back immediately), this "EE" version stays in the down position when pressed and requires a second press to return to the original state. #### C. Dual-Color LED Configuration This specific model features a **Bi-color** setup (Red/Blue). * **LED 1 (Red):** Typically indicates a "Warning," "Record," or "Active" state. * **LED 2 (Blue):** Typically indicates "Power On," "Standby," or "Bluetooth" connectivity. --- ### 3. Technical Specifications | Parameter | Value | | :--- | :--- | | **Contact Rating** | 100mA @ 30VDC | | **Contact Resistance** | 50 mΩ Max (Initial) | | **Insulation Resistance** | 100 MΩ Min @ 500VDC | | **Dielectric Strength** | 500VAC for 1 minute | | **Operating Life** | 50,000 Cycles | | **Travel** | Full: 3.0mm / Lock: 2.0mm | --- ### 4. Typical Applications * **Professional Audio:** Mixer consoles, signal processors, and amplifiers. * **Test & Measurement:** Multi-state toggling for laboratory equipment. * **Computing:** High-end peripheral controls or server reset/power buttons.
