The **LP4-EE-1-R-W-A-R-B** is a specific part number for a push-button switch manufactured by **E-Switch**. This component belongs to the LP4 series, which is known for its right-angle, surface-mount (or through-hole) illuminated design.
### Component Breakdown
The part number is an alphanumeric code where each segment defines a specific physical or electrical characteristic:
| Segment | Feature | Description |
| :--- | :--- | :--- |
| **LP4** | Series | Right-angle, illuminated pushbutton switch |
| **EE** | Function | Latching (Push-on, Push-off) mechanism |
| **1** | Housing | Standard housing style |
| **R** | Terminal Style | Right-angle PC pin mounting |
| **W** | Actuator Style | Large square cap (typically 12mm x 12mm) |
| **A** | Operating Force | Standard operating force (approx. 300gf) |
| **R** | LED 1 Color | Red LED illumination |
| **B** | LED 2 Color | Blue LED illumination (Bi-color) |

### Features & Applications
This component is highly specialized for interfaces requiring visual feedback and robust mechanical switching.
#### Key Features:
1. **Bi-Color Illumination:** The "R-B" designation indicates Red and Blue LEDs, allowing the switch to change colors based on the state of the circuit.
2. **Latching Action:** Unlike momentary switches, the "EE" designation means it stays in the depressed position until pressed again.
3. **Right-Angle Mounting:** Designed to be mounted on a PCB such that the button faces the side of the enclosure (ideal for edge-mounting).
#### Common Applications:
* **Audio/Visual Equipment:** Mixer consoles and signal processors.
* **Test & Measurement:** Handheld or benchtop diagnostic tools.
* **Telecommunications:** Network hubs or server hardware.
* **Industrial Controls:** Status indicators for machinery.
