The part number **LP4-EE-1-P-G-C-R-R** refers to a high-quality, illuminated pushbutton switch manufactured by **E-Switch**. It belongs to the LP4 series, which is known for its right-angle mounting and various LED illumination options. ### 1. Part Number Breakdown To understand the electronic components of this specific part, we must decode the suffix codes: | Code Segment | Feature | Description | | :--- | :--- | :--- | | **LP4** | Series | Right-angle, PC board mount pushbutton switch | | **EE** | Function | Latching (Push-on, Push-off) | | **1** | Contact Arrangement | DPDT (Double Pole Double Throw) | | **P** | Terminal Type | PC Pin (Through-hole) | | **G** | Bezel/Actuator | Square cap (usually clear or translucent) | | **C** | Actuator Color | Clear | | **R** | LED 1 Color | Red LED | | **R** | LED 2 Color | Red LED | --- ### 2. Key Technical Specifications The electrical performance and mechanical lifecycle of the LP4 series are summarized below: | Specification | Value | | :--- | :--- | | **Current Rating** | 100mA @ 30VDC | | **Circuitry** | DPDT (Double Pole Double Throw) | | **Actuation Force** | 200 ± 50 grams | | **Travel** | 3.30mm (Full), 2.50mm (Lock) | | **Contact Resistance** | 50 mΩ Max (Initial) | | **Insulation Resistance** | 100 MΩ Min @ 500VDC | | **Operating Temp** | -20°C to +70°C | | **Lifecycle** | 50,000 Cycles | --- ### 3. Electronic Design Features * **Dual LED Illumination:** This specific model features two **Red LEDs**. Because it is DPDT, the switch can control two separate circuits while providing visual feedback. * **Latching Mechanism:** Unlike momentary switches, the "EE" designation means the switch stays in the depressed position until pressed a second time. This is ideal for power toggles or mode selections. * **Right-Angle Mounting:** The pins are oriented at 90 degrees, allowing the button to be mounted on the edge of a Printed Circuit Board (PCB) and protrude through a front panel. * **DPDT Logic:** With six pins for the switch and additional pins for the LEDs, this allows for complex signal routing (e.g., swapping between two different signal paths). --- ### 4. Typical Applications * **Audio/Visual Equipment:** Mixing consoles and signal processors. * **Industrial Controls:** Panel-mounted status indicators. * **Telecommunications:** Network hardware interface buttons. * **Instrumentation:** Testing and measurement device power switches.
