Based on the technical nomenclature for high-end electronic components, the part number **LP4-EE-1-R-G-B-T-R** typically refers to a multi-color illuminated pushbutton switch (often associated with manufacturers like E-Switch or similar industrial component suppliers). Below is the breakdown of the electronic specifications and features. ### Component Breakdown | Code | Category | Description | | :--- | :--- | :--- | | **LP4** | Series | Low-profile, panel-mount illuminated pushbutton switch. | | **EE** | Function | Latching (Push-on, Push-off) or Alternate Action. | | **1** | Housing/Circuit | SPDT (Single Pole Double Throw) configuration. | | **R-G-B** | LED Colors | Triple LED configuration: **Red, Green, and Blue**. | | **T** | Transparency | Transparent cap/button style for light diffusion. | | **R** | Bezel/Finish | Usually denotes a Round bezel or a specific RoHS compliance marker. | --- ### Technical Specifications #### 1. Electrical Ratings * **Contact Rating:** Typically 100mA @ 30VDC. * **Contact Resistance:** 50m$\Omega$ (maximum initial). * **Insulation Resistance:** 100M$\Omega$ at 500VDC. * **Dielectric Strength:** 500VAC for 1 minute. #### 2. LED Characteristics The **RGB** designation indicates that this switch contains three independent LED dies. By varying the voltage/current to each pin, the user can create multiple colors (White, Magenta, Cyan, etc.). * **Forward Voltage ($V_f$):** * Red: ~2.0V * Green: ~3.3V * Blue: ~3.3V * **Forward Current:** Typically 20mA per channel. #### 3. Mechanical Properties * **Actuation Force:** ~150 to 250 grams. * **Travel Distance:** Total travel is usually around 1.5mm to 2.5mm. * **Operating Life:** Rated for 50,000 cycles (minimum). --- ### Terminal Pinout (General Layout) Because this is an RGB Latching switch, it usually features 7 to 8 pins: 1. **Switch Terminals (3 pins):** Common (C), Normally Open (NO), and Normally Closed (NC). 2. **LED Terminals (4 pins):** Common Anode or Cathode, plus individual pins for Red, Green, and Blue. --- ### Common Applications * **Audio/Visual Equipment:** For mode selection (e.g., "Record" turns red, "Ready" turns green). * **Industrial Control Panels:** Status indication via color coding. * **Test & Measurement:** Compact interfaces requiring multi-state feedback.
