AI Technical Summary
Existing membrane switches and circuit products suffer from problems such as insufficient connection strength and easy breakage of circuits during the insertion process. The lack of visual insertion guidance and scientific size matching design leads to product malfunction and shortened service life.
A Mark line identification line is set on the reinforcing plate, and the size fit between the carbon ink layer and the reinforcing plate is optimized. The Mark line identification line indicates the insertion status. The reinforcing plate is designed with D1=D0+0.8mm to protect the carbon ink layer. Glass fiber reinforced epoxy resin board is used as the material of the reinforcing plate.
It improves the reliability of the connection and the service life of the product, reduces the failure rate and labor costs, and enhances production efficiency and batch stability of the product.
