The part number **47LPQ-D2W-R** corresponds to a high-quality **Illuminated Pushbutton Switch** manufactured by **Grayhill**. This specific series is designed for panel mounting where space is limited and tactile feedback is required. --- ## 1. Technical Specifications Below are the primary technical parameters for the 47LPQ series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Pushbutton | | **Circuitry** | DPDT (Double Pole Double Throw) | | **Switch Function** | Momentary (On) | | **Current Rating** | 0.4 VA max @ 20V AC/DC | | **Illumination** | LED (Bi-color or Single) | | **Termination Style** | Right Angle PC Pin (Horizontal Mount) | | **Mounting Type** | Through Hole | --- ## 2. Part Number Breakdown Understanding the suffix codes helps identify the specific features of this component: ### **47LPQ (Series Prefix)** * **47L:** Refers to the sub-miniature sealed pushbutton series. * **P:** Denotes a panel mount or specific plunger style. * **Q:** Indicates a specific contact material (often Silver over Nickel or Gold over Nickel for low-level logic). ### **D2W (Configuration)** * **D:** Represents the circuit configuration (DPDT). * **2:** Usually indicates the specific LED color or intensity (often Red/Green or White). * **W:** Refers to the cap style or wire/pin arrangement. ### **R (Packaging/Orientation)** * **R:** Specifically indicates **Right Angle** mounting. This means the switch is mounted on a PCB horizontally, but the button faces the user vertically relative to the board. --- ## 3. Key Features and Applications * **Sealing:** The "47L" series is typically sealed to **IP67** standards, making it resistant to dust and water ingress. * **Compact Design:** The sub-miniature footprint is ideal for handheld devices and dense control panels. * **Tactile Feedback:** Provides a crisp, clear snap-action feel so the user knows the switch has been actuated. * **Common Uses:** * Industrial control systems. * Medical instrumentation. * Test and measurement equipment. * Telecommunications hardware. --- ## 4. Mechanical Drawing Concepts Since this is a **Right Angle (R)** part, the physical orientation is as follows: ```text [ Button Cap ] | [ Switch Body ] ---- [ Pins bent 90 degrees ] | [ PC Board Surface ] ```
