Membrane switch Structure
1.Graphic Overlay – PET/PC is usually the material of choice due to its superior
chemical
resistance and flex life . MEIBORUI can either digitally print,
screen-print, or employ a
combination of both methods to ensure you get the right colors,
textures and finishes your
design requires.
2. Overlay Adhesive – This adhesive layer bonds the graphic overlay to the top circuit
layer,
and is typically an acrylic adhesive. The material is same as the
fourth layer. Only the
thickness will be different according to the physical truth.
3. Top Circuit Layer – The material of this layer is special. This is a 0.1mm heat
stabilized
PET printed with silver-filled electrically conductive inks and
also dielectric inks, which used
for fastening metal domes.
4. Circuit Spacer – This layer separates the top circuit from the bottom circuit so
the switch
remains normally open until the keypad is pressed. The circuit
spacer is a polyester spacer
with adhesive on both sides.
5.Lower Circuit Layer – This layer is a 0.1mm--0.25mm heat stabilized polyester printed
with silver-filled electrically conductive inks and also dielectric
inks. This layer terminates as a
flexible tail that serves as the interconnect to controller PCBs or
other electronics.
6.Rear Adhesive Layer – This adhesive layer bonds the entire membrane switch package to
the product enclosure, housing, or to a rigid support panel.
MEIBORUI can specify the
appropriate adhesive type and thickness to bond your membrane
keypad to your equipment.
