Product Name: KCD4 Series Lighted Rocker Switch (2-Pin, Light Bulb Icon Model)

Appearance and Structural Features:

Overall Structure: This is a black square rocker switch belonging to the KCD4 series. Its most distinctive feature is the red translucent rocker with a white "light bulb" icon printed on it, clearly indicating its primary use for lighting control.
Indicator Light Design: The rocker itself serves as a light guide. When the switch is on, the built-in neon bulb or LED lights up the entire red panel, serving both as an indicator of the switch status and providing decorative and nighttime visibility.

Materials and Manufacturing:

Body: Made of black high-temperature resistant engineering plastic (usually nylon PA66) with anti-slip textured sides, ensuring durability and robustness.
Contact Pins: Two metal terminal pins at the bottom (plug-in type). This 2-pin design is the basic single-pole single-throw (SPST) structure, providing simple on/off control.

Functional Design (Key Features):

Electrical Specifications: According to the laser marking on the body, this switch has high load capacity:
16A 250V AC (suitable for most household appliance voltages)
20A 125V AC (suitable for low-voltage high-current applications)
Model Identification: The "KCD4" is clearly printed on the side of the body, which is an industry-standard mold code for easy replacement and procurement.
Mounting Method: Snap-fit mounting, which can be fixed with a standard rectangular cutout without the need for screws, making installation convenient.
Dimension Specifications (based on drawing markings):
Panel Size: Approximately 21.5mm x 15.2mm.
Overall Height: Approximately 26.5mm (including pins).
Cutout Size: Typically requires a rectangular cutout of about 19mm x 13mm (please refer to detailed specifications for exact requirements, but this can be inferred based on the panel size).
