The **LP4-EE-1-P-B-C-R-R** is a specific part number for a push-button switch, typically manufactured by companies like **E-Switch** (LP4 series). This component is designed for panel mounting and is known for its integrated LED illumination and right-angle PCB mounting capability. --- ### 1. Technical Specifications Breakdown The part number follows a specific nomenclature. Below is the breakdown of its primary electronic and physical characteristics: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Circuitry** | DPDT | Double Pole Double Throw (6 pins for switching) | | **Switch Function** | Latched (EE) | Push-on, Push-off (stays in position) | | **Mounting Type** | Through-hole | Right-angle PCB mounting | | **Illumination** | LED | Integrated Red LED | | **Current Rating** | 100mA | Rated for low-current signal switching | | **Voltage Rating** | 30V DC | Standard for control logic circuits | | **Actuation Force** | 200 ± 50 gf | Moderate pressure required to actuate | --- ### 2. Component Features * **Illumination Strategy:** The "R-R" in the suffix usually denotes the LED color and the cap color (Red LED / Red Cap). This provides visual feedback to the user when the circuit is active. * **DPDT Logic:** Having two poles allows the switch to control two independent circuits simultaneously. For example, one pole can handle the signal logic while the second pole controls an external indicator light. * **Mechanical Durability:** These switches are generally rated for approximately 50,000 to 100,000 cycles, making them suitable for industrial control panels. --- ### 3. Pin Configuration and Wiring Typical for the LP4 series, the pinout is arranged for PCB stability: 1. **Switch Terminals (6 pins):** Arranged in two rows of three. * *Common (C), Normally Open (NO), Normally Closed (NC)* for each pole. 2. **LED Terminals (2 pins):** Independent of the switch terminals. * Requires a current-limiting resistor if the supply voltage exceeds the LED's forward voltage (usually ~2.0V for Red). --- ### 4. Applications * **Audio/Visual Equipment:** Channel toggling or power state selection. * **Industrial Controls:** Mode selection on control interfaces. * **Test & Measurement:** Activating specific measurement loops in a device.
