Key Product Features
-
High-Capacity AC 240V Rating: Optimized for standard mains power, providing a secure and stable switching solution for home appliances, workshop tools, and industrial equipment.
-
3-Pin Terminal Configuration: Equipped with three high-conductivity male spade terminals for versatile wiring. This configuration typically supports Single Pole Single Throw (SPST) operation with a ground/neutral connection for indicator support.
-
Compact 19.90mm Mounting: Features a precision $19.90\text{mm}$ circular face, making it an ideal space-saving choice for dense control panels and custom DIY project boxes.
-
Quick Snap-In Installation: Integrated flexible plastic mounting ribs allow the switch to be securely "snapped" into a standard panel cutout without the need for additional fasteners or tools.
-
Intuitive "I/O" Operation: The rocker actuator is laser-printed with high-contrast international symbols for "ON" (I) and "OFF" (O), ensuring clear user operation at a glance.
-
Rugged Black Chassis: Built with a high-impact, heat-resistant plastic housing that protects the internal contacts from dust and environmental wear.

Top 3 Customer Questions & Concerns �
� What is the purpose of the 3rd pin on this specific black model?
While 3-pin switches often feature an internal light, the third pin on a non-illuminated model can serve as a ground terminal for increased safety or a common junction point in specific circuit designs. Always consult your circuit diagram to ensure the proper pin is connected to your neutral or load line.
Are the terminals compatible with standard connectors?
Yes. These pins are designed to fit standard female spade (crimp) connectors. This allows for a solderless installation, which is faster and easier to maintain or replace in the future.
� Can this switch be used in 12V DC systems?
While rated for AC 240V, the mechanical switching action will work in a DC environment. However, users should be aware that the internal components are optimized for AC current; when used with DC, ensure your amperage does not exceed the switch's mechanical capacity to avoid contact pitting.
