Waterproof Membrane Switch memrbrane keypad with 3M adhesive
A membrane switch consists of various layers laminated together.
The layers of a basic membrane switch construction include a
membrane overlay, spacer, printer circuit, rear adhesive, and tail
filler. The membrane switches environment and requirements can vary
the way the switches plug into its interface. For example, if
shielding is necessary, a two-circuit membrane switch design would
be a better construction choice. Replace the printed silver circuit
with a copper and polyimide construction for more stringent
environmental requirements. These construction designs are often
called “Kapton” circuits. These circuits offer an advantage over
current carrying capacity and better resistance to moisture. You
can explore more construction possibilities by downloading our
membrane switch design guide or contacting us for support.
Embossed polyester tactile domes cost less for high volume parts
with many keys.
They can be formed in the overlay or hidden inside internal layers.
Non-tactile keys are the least expensive and longest lasting.
