Installation & Usage Guide
This product is a flat-style metal dome switch designed for direct mounting onto corresponding contacts on a printed circuit board (PCB). To simplify assembly and ensure positional accuracy, we highly recommend using this product with customized PET adhesive films (metal dome switch keypad stickers). These PET stickers can pre-fix single or multiple domes accurately, forming an entire row or matrix of keys. Installation is completed with a single application, significantly improving production efficiency and yield.

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