Top 3 Customer Questions & Concerns �
� Why does this switch have 4 pins instead of 2?
The 4-pin design is a safety-first configuration. While a 2-pin switch only cuts one wire, this 4-pin model cuts both wires entering the device. This ensures that no residual current remains in the appliance when it is turned off, significantly reducing the risk of electrical shock during maintenance.
Does the light work on both AC and DC systems?
The illuminated models (Red/Green/Blue) contain internal lamps that are typically optimized for AC mains power ($220\text - 250\text$). If used in a low-voltage DC system (like a $12\text$ car battery), the switch will function perfectly as a mechanical power control, but the internal light may not glow or will appear very dim.
� How do I wire the indicator light correctly?
For the light to function, the 4 pins must be wired as pairs. One side of the switch takes the incoming power (Line/Neutral), and the opposite side connects to your device. When the rocker is flipped to the "I" position, it bridges the internal lamp across the power lines, causing it to illuminate automatically.
