The **KWDNY-3CD-R** is a specific model of a **Rocking Switch (or Boat Switch)** commonly used in household appliances, power strips, and industrial equipment. It is characterized by its integrated light indicator and rectangular snap-in design. --- ### 1. Technical Specifications Below are the typical electronic ratings for this specific component: | Feature | Specification | | :--- | :--- | | **Model Number** | KWDNY-3CD-R | | **Contact Configuration** | Single Pole Single Throw (SPST) | | **Rated Voltage/Current** | 15A 250V AC / 20A 125V AC | | **Illumination** | Internal Neon or LED Lamp (Red) | | **Terminal Type** | 3-Pin (Power, Load, Ground/Neutral for Light) | | **Mounting Style** | Snap-in Panel Mount | --- ### 2. Physical Components & Materials The switch is constructed from several distinct layers designed for safety and durability: * **Actuator (Rocker):** Usually made of Polycarbonate (PC). The "R" in the model suffix often denotes the color **Red**. * **Housing:** Made of Nylon 66 (UL94V-2 flame retardant plastic). * **Contacts:** Silver-plated copper alloy to ensure high conductivity and minimize arcing. * **Terminals:** Brass with tin or silver plating for easy soldering or quick-connect spade terminals (6.3mm). --- ### 3. Pinout & Internal Wiring Since this is a **3-pin** illuminated switch, the wiring is crucial for the internal light to function correctly: 1. **Pin 1 (Line/Hot):** Input power from the source. 2. **Pin 2 (Load):** Outgoing power to the device/appliance. 3. **Pin 3 (Neutral):** This pin is specifically for the **internal lamp**. It must be connected to the Neutral wire to complete the circuit for the light to glow when the switch is "ON". --- ### 4. Common Applications * **Power Strips/Surge Protectors:** Acts as the main power toggle and "power on" indicator. * **Kitchen Appliances:** Used in coffee makers, air fryers, and electric kettles. * **Industrial Panels:** Used as a simple control switch for motors or lighting circuits. * **DIY Electronics:** Frequently used in custom enclosures for power management. ---
