The **LP4-EE-1-R-B-N-R-B** is a specific part number for a push-button switch manufactured by **E-Switch**. This series is known for its high-quality illumination and customizable options for panel-mount applications. --- ## Technical Specifications Breakdown The part number is a coded string where each segment represents a specific physical or electrical characteristic. ### Part Number Decoder | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | LP4 | Illuminated Pushbutton Switch (Right Angle/Straight) | | **Function** | EE | Latching (Push-on, Push-off) | | **Contact** | 1 | DPDT (Double Pole Double Throw) | | **Mounting** | R | Right Angle PC Pin Terminal | | **Cap Style** | B | Square Cap (Translucent) | | **Bezel** | N | No Bezel | | **LED 1 Color** | R | Red LED | | **LED 2 Color** | B | Blue LED | --- ## Key Features ### 1. Circuitry: DPDT (Double Pole Double Throw) This means the switch can control two separate circuits simultaneously. Each "pole" can toggle between two different "throws" (outputs), providing versatility for complex signal routing. ### 2. Operation: Latching (Maintained) The "EE" designation indicates a latching mechanism. When pressed, the switch stays in the "down" position until pressed a second time to release it. This is ideal for power toggles or mode selections. ### 3. Dual-LED Illumination This specific model features a **Red/Blue** dual-LED configuration. * **LED 1 (Red):** Typically used for an "Active" or "Alarm" state. * **LED 2 (Blue):** Typically used for a "Standby" or "Power-On" state. * The cap is translucent to allow the light to diffuse evenly. ### 4. Right Angle Mounting The "R" mounting style indicates that the pins are bent at a 90-degree angle. This is designed for edge-mounting on a Printed Circuit Board (PCB), allowing the button to face outward from the side of a device enclosure. --- ## Electrical Ratings | Parameter | Value | | :--- | :--- | | **Contact Rating** | 100mA @ 30VDC | | **Electrical Life** | 50,000 Cycles | | **Contact Resistance** | 50mΩ Max (Initial) | | **Insulation Resistance** | 100MΩ Min @ 500VDC | | **Dielectric Strength** | 500VAC for 1 Minute | | **Operating Force** | 200 ± 50 gf | --- ## Common Applications * **Audio/Visual Equipment:** Signal routing and channel selection. * **Telecommunications:** Network hardware toggles. * **Instrumentation:** Industrial control panels. * **Medical Electronics:** Interface buttons requiring clear visual feedback.
