1. The membrane switch is required to keep the surface clean. At the same time, there must be no bulge, and proper dust prevention and anti-oil treatment should be carried out.
2. Comparing the size of the film (whether the film switch is placed in the place to be posted or the size of the film is not coincident);
3. Then remove the centrifugation paper under the membrane switch from the edge and remove it by one centimeter;
4. Then place the membrane switch in the corresponding orientation to a part, and then gradually tear off the remaining centrifugal paper (but not to exceed 15 degrees), and then place it in the corresponding position. .
5. If the membrane switch to tear off the centrifugation paper during the posting process needs to be placed first, it should not be placed upwards to prevent sticking to other objects and affecting the posting;
6. Posting can not be repeated operation, one-time end; pay attention to control the angle of tearing; try touch feel, should be placed in a flat place, can not be held in the hand, otherwise it will be very easy to damage the membrane switch.
