The part number **LP4-EE-1-R-G-A-N-R** refers to a specific configuration of an illuminated push-button switch, typically manufactured by companies like **E-Switch** (LP4 series). This series is known for its right-angle mounting and high-quality LED illumination. ### Part Number Breakdown The following table breaks down each segment of the part number based on standard LP4 series nomenclature: | Code Segment | Feature | Description | | :--- | :--- | :--- | | **LP4** | Series | Right-angle, illuminated pushbutton switch | | **EE** | Function | Latching (Push-on, Push-off) | | **1** | Housing | Style 1 (Standard square housing) | | **R** | Cap Color | Red | | **G** | LED 1 Color | Green | | **A** | LED 2 Color | Amber (Dual LED configuration) | | **N** | Legend | None (No text/symbols on cap) | | **R** | Terminal Plating | RoHS compliant/Silver plating | --- ### Technical Specifications These components are generally used in consumer electronics, telecommunications, and testing equipment. Below are the typical electrical and mechanical characteristics for this series: #### 1. Electrical Characteristics * **Contact Rating:** 100mA @ 30VDC * **Contact Resistance:** 50m$\Omega$ Max (Initial) * **Insulation Resistance:** 100M$\Omega$ Min @ 500VDC * **Dielectric Strength:** 500VAC for 1 minute #### 2. Mechanical & Environmental * **Operating Life:** 50,000 cycles * **Travel:** Full travel: ~3.0mm; Lock travel: ~2.0mm * **Operating Force:** 150gf to 250gf * **Operating Temperature:** -20°C to +70°C --- ### Internal Circuitry & Mounting The "LP4" series is specifically designed for **PCB (Printed Circuit Board)** mounting. * **Mounting Orientation:** Right-angle. This means the button face is perpendicular to the PCB surface, making it ideal for edge-mounting on devices where the user interacts with the side of the enclosure. * **Dual Illumination:** This specific model uses a dual LED setup (Green/Amber). Depending on the wiring, the switch can glow one color when inactive and another when active, or change based on external logic. * **Latching Action:** The "EE" designation indicates that once pressed, the switch stays in the "down" position until pressed again to release. --- ### Typical Applications * **Audio/Visual Equipment:** Channel switching or power buttons. * **Industrial Controls:** Status indicators for machinery. * **Computer Peripherals:** Reset or mode-selection buttons. * **Instrumentation:** Menu navigation and power toggles.
