Membrane Keypads
Produced from chemical resistant polycarbonate or cost
effective polyester, membrane switches are available in
a variety of colors and configurations. Made from
layers of insulating materials and conductive inks,
membrane switches are completely integrated switching
systems. Their low profile and available self-adhesive
backing make membrane switches ideal for small spaces
and outdoor applications.
Rubber Keypads
|
Produced from chemical resistant, nontoxic silicone compounds;
rubber keypads are available in a variety of colors and configurations.
Nonconductive rubber is used for the keys and conductive rubber is used
for the pill inserts. When used in conjunction with copper contacts
etched in a printed circuit board, a wide variety of switching
configurations can be accomplished. Rubber keypads can be integrated with
membrane switches in applications where a printed circuit board is not
available.
