The **LP4-EE-1-R-W-A-N-R** is a specific part number for a push-button switch, typically manufactured by companies like **E-Switch** (LP4 series). This series is known for being a panel-mount, illuminated, rectangular pushbutton switch. Below is a detailed breakdown of the electronic and physical characteristics based on the part numbering nomenclature. --- ## Technical Specifications | Feature | Description | | :--- | :--- | | **Switch Type** | Pushbutton (Momentary or Latching) | | **Circuit** | DPDT (Double Pole Double Throw) | | **Illumination** | LED Integrated | | **Mounting Type** | Through-hole (PCB) or Panel Mount | | **Actuation Force** | ~150 to 250 grams | | **Contact Rating** | Usually 100mA @ 30VDC | --- ## Part Number Breakdown (LP4-EE-1-R-W-A-N-R) | Code | Segment | Meaning | | :--- | :--- | :--- | | **LP4** | Series | Low profile, illuminated pushbutton series. | | **EE** | Function | Latching (Push-on, Push-off) function. | | **1** | Housing | Style 1 (Standard rectangular housing). | | **R** | Cap Color | **Red** Transparent/Translucent cap. | | **W** | LED 1 Color | **White** LED illumination. | | **A** | LED 2 Color | No second LED or specific Amber configuration (varies by mfg). | | **N** | Legend | No legend (Blank cap). | | **R** | RoHS | Compliant with RoHS environmental standards. | --- ## Key Features ### 1. Mechanical Function (EE) The "EE" designation indicates a **Latching** mechanism. When pressed, the switch stays in the "down" position until pressed a second time to release. This is commonly used for power toggles. ### 2. Electrical Configuration (DPDT) The Double Pole Double Throw (DPDT) configuration allows the switch to control two separate circuits simultaneously. Each "pole" can toggle between two different output paths. ### 3. Illumination This model features integrated LED lighting. Because it is specified with "W" (White), the switch will glow white when the internal LED is powered. Note that the LED usually requires a current-limiting resistor to prevent burnout. ### 4. Compact Design The "LP" stands for **Low Profile**, making it ideal for sleek control panels, audio/visual equipment, and handheld instrumentation where space is limited. --- ## Pinout Diagram Concept ```text [ LED Pins ] [ Switch Terminals ] (+) (-) (1) (2) (3) <-- Pole A (4) (5) (6) <-- Pole B ``` *Note: Terminals 2 and 5 are typically the "Common" pins.*
