1. Clean the surface of the membrane switch to be fitted.
2, the size of the comparison.
3, then peel the centrifugal paper at the bottom of the membrane switch from the side by about 10mm
4, then put the membrane switch to the corresponding position to stick a part, then slowly tear off the remaining centrifugal paper, and then paste it to the corresponding position.
5. If the membrane switch that tears off the reverse centrifugal paper needs to be placed first, it should be placed on the reverse side to prevent sticking to other objects.
