Our company have three comment structures as follows
Structure One : RUBBER + PET + SPACER + CONDUCTIVE POINT
1.RUBBER
2.DOME(PET)
3.Spacer
4.Conductive Point ( silver / carbon paste )
SPACER is single-sided adhesive, POLY DOME sticky silicone. It can be firmly attached to the Keypad and is not easy to tear off. It is also called as Stick type Conductive Point.
Structure Two: PE+SPACER+CONDUCTIVE POINT
1.DOME(PET)
2.Spacer
3.Conductive Point ( silver / carbon paste )
SPACER is double-sided adhesive, POLY DOME sticky PCB board
Structure Three : PET+SPACER+CONDUCTIVE POINT
1.DOME(PET)
2.Spacer
3.Conductive Point ( silver / carbon paste )
SPACER is single-sided adhesive, POLY DOME card assembly
