Navigation module

The multi-functional and modular design integrates multiple identical switch units, with different caps and subsequent paint, laser engraving and other processes, to form a multi-button button module and integrate the contacts to reduce pins, or combine different functions The switch integrates a human-machine interface control module such as an LCD display panel with a rotary encoder and button switch. The switch button is also modularized to derive Shangpu's patented versatile smart cover, allowing an application to be shadowed on the cover. Depending on the switch body, the same switch can be matched with caps of different styles, sizes, and shapes.
