The **W2AP-32D-R/N** is a specialized industrial-grade push-button switch, typically part of a control series used in automation, panels, and machinery. Based on the model nomenclature, it belongs to the **Ø22mm (22 millimeter)** mounting diameter family. ### 1. Technical Specifications The table below highlights the core electronic and mechanical parameters for this specific part: | Parameter | Specification | | :--- | :--- | | **Mounting Diameter** | 22mm (Standard Industrial Size) | | **Actuator Type** | Extended Push Button (Non-illuminated) | | **Contact Configuration** | 1NO + 1NC (1 Normally Open + 1 Normally Closed) | | **Operation Mode** | Momentary (Spring Return) | | **Rated Voltage** | 250V AC / DC | | **Rated Current** | 10A (Thermal Current $I_{th}$) | | **Color Code** | R/N (Red / Green or specific indicator variants) | | **Protection Rating** | IP65 (Dust-tight and water-jet resistant) | --- ### 2. Breakdown of the Model Name Industrial parts often use an alphanumeric code to define their physical and electrical characteristics: * **W2AP**: Refers to the series (likely the **W** series 22mm Plastic/Metal range). * **32D**: Indicates the actuator shape (Extended head) and specific physical dimensions. * **-R/N**: * **R**: Red (Color of the button). * **N**: Represents the contact block type or a specific standard compliance (often indicates the inclusion of both NO and NC blocks). --- ### 3. Electronic Components & Internal Construction The device consists of three primary electronic/mechanical modules: #### A. The Actuator (Head) The mechanical interface that the operator presses. In the "32D" variant, this is usually an "extended" button, making it easier to press even with gloves, compared to "flush" buttons. #### B. Contact Blocks This is where the electrical switching occurs. The W2AP series uses modular contact blocks: * **Normally Open (NO):** Circuit is incomplete until the button is pressed. * **Normally Closed (NC):** Circuit is complete until the button is pressed (often used for stop functions). #### C. Terminals * **Screw Terminals:** Designed for secure wire connection using ferrules or ring lugs. * **Material:** Conductors are usually made of silver alloy to minimize contact resistance and prevent oxidation over high-cycle use. --- ### 4. Typical Applications * **Motor Control:** Starting or stopping industrial motors. * **Control Panels:** Manual interface for PLC (Programmable Logic Controller) inputs. * **Safety Interlocks:** Used in low-risk signal circuits to interrupt power.
