8. FAQ
What standards apply to this product?
KAN428 Series is qualified to GJB1512A-2011 (Pushbutton Switch General Specification), with execution standards Q/MA 20306-2014 (Standard grade) and Q/QJA 20122/6-2018 (YC aerospace grade).
Are the LED indicator color and display symbols customizable?
Yes. Standard configuration uses green illumination. Custom colors (red, blue, yellow, white, dual-color) and custom display symbols/characters are available per customer specification.
What is the difference between voltage-drive (GV) and current-drive (GI)?
Voltage-drive (GV): Direct voltage operation, ideal for regulated DC supplies. Current-drive (GI): Current-regulated brightness, handles supply voltage variation better.
