Installation & Usage Instructions
This product is a flat single-contact metal dome switch designed for use on printed circuit boards (PCBs). During installation, align it with the pre-designed single circuit contact on the PCB. To improve assembly efficiency and consistency, we recommend using customized PET adhesive films (metal dome switch keypad stickers) for fixation, which is particularly suitable for high-volume production of multi-key arrays.

Please Note: We can customize and produce multi-dome PET keypad stickers incorporating this model based on your specific application requirements and PCB layout drawings.
