The **LP4-OA-1-R-G-A-R-Y** is a specific part number for a high-quality illuminated pushbutton switch, typically manufactured by **E-Switch**. This component is widely used in control panels, audio equipment, and industrial interfaces. Below is a breakdown of the electronic and mechanical specifications based on the alphanumeric code. --- ### 1. Part Number Breakdown The part number defines the physical and electrical characteristics of the switch: | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | LP4 | Low profile, illuminated pushbutton switch | | **Circuit** | OA | Momentary (Non-locking); DPDT (Double Pole Double Throw) | | **Housing** | 1 | Standard housing style/mounting | | **LED 1** | R | Red LED (First illumination color) | | **LED 2** | G | Green LED (Second illumination color) | | **Cap Style** | A | Square Cap | | **Cap Color** | R | Red Translucent | | **Legend** | Y | "Standby/Power" Symbol or specific custom graphic | --- ### 2. Electrical Specifications This switch is designed for low-power signal switching rather than high-voltage power lines. * **Contact Rating:** 100mA @ 30VDC * **Contact Resistance:** 50mΩ Max (initial) * **Insulation Resistance:** 100MΩ Min at 500VDC * **Dielectric Strength:** 500VAC for 1 minute * **Electrical Life:** 50,000 Cycles --- ### 3. Mechanical & Environmental Features * **Operating Force:** 150 ± 50 gram-force. * **Travel:** Total travel is approximately 1.5mm. * **Operating Temperature:** -20°C to +70°C. * **Termination:** Through-hole PC Pin (designed for soldering onto a Printed Circuit Board). --- ### 4. Internal Circuitry (DPDT) The **DPDT (Double Pole Double Throw)** configuration means the switch controls two separate circuits simultaneously. When pressed: 1. The first set of contacts switches from Normally Closed (NC) to Normally Open (NO). 2. The second set of contacts does the same. 3. Because it is **Momentary (OA)**, the contacts spring back to their original position as soon as you release the button. --- ### 5. LED Configuration The "R-G" designation indicates a **Bi-color LED** setup. * **Red LED:** Typically used for "Off" or "Fault" status. * **Green LED:** Typically used for "On" or "Ready" status. * The LEDs are independent of the switch circuit; they must be powered separately via the dedicated LED pins on the bottom of the component.
