The **LP4-EE-1-P-G-N-R-R** is a specific part number for a push-button switch, typically manufactured by **E-Switch**. It belongs to the LP4 series, which is known for its right-angle mounting and integrated LED illumination. Below is a breakdown of the electronic components and specifications based on the part numbering scheme. --- ## 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Series** | LP4 (Illuminated Pushbutton) | | **Circuit Type** | DPDT (Double Pole Double Throw) | | **Switch Function** | Latched (Push-On, Push-Off) | | **Current Rating** | 100mA @ 30VDC | | **Contact Resistance** | 50mΩ Max (initial) | | **Insulation Resistance** | 100MΩ Min @ 500VDC | | **Dielectric Strength** | 500VAC for 1 minute | | **Operating Force** | 200 ± 50 gf | | **Travel** | 3.30mm (Full), 2.50mm (to lock) | --- ## 2. Part Number Breakdown The alphanumeric code represents specific hardware configurations: ### `LP4` - Series Indicates the base series of the illuminated pushbutton switch. ### `EE` - Circuit / Function * **EE:** Signifies a **DPDT** circuit with **Latching** action (Maintenance). The button stays down when pressed and returns when pressed again. ### `1` - Housing Style * Refers to the physical frame/housing of the switch, typically designed for PC Board mounting. ### `P` - Terminal Type * **P:** PC Pin (Through-hole) mounting. This is meant for soldering directly onto a Printed Circuit Board. ### `G` - Bracket/Actuator Style * **G:** This usually denotes a specific mounting bracket, often a **Right Angle** orientation, allowing the button to be pressed from the side of the PCB. ### `N` - Cap Style * **N:** No Cap / Square Cap (depending on specific catalog revision). In many E-Switch configurations, 'N' implies a standard square bezel. ### `R-R` - Illumination Colors * **R (LED 1):** Red LED. * **R (LED 2):** Red LED. * This indicates a dual-LED setup where both light sources are Red. --- ## 3. Terminal Layout (DPDT) The DPDT configuration involves 6 primary switch pins and additional pins for the LEDs: ```text Switch Terminals: [1] [2] [3] (Pole 1: NC, COM, NO) [4] [5] [6] (Pole 2: NC, COM, NO) LED Terminals: [+] [-] (Red LED 1) [+] [-] (Red LED 2) ``` --- ## 4. Key Application Notes * **Signal Level Only:** With a rating of 100mA at 30VDC, this switch is designed for logic signals and low-power control circuits, not for switching mains AC power. * **LED Protection:** The integrated LEDs require external current-limiting resistors to prevent burnout. * **Mounting:** The right-angle design is ideal for edge-of-board placement in consumer electronics, test equipment, or medical devices.
