Silicone rubber keypads are also known as
Elastomeric Keypads. They have been used in many
consumer and industrial electronic products
because of its low cost and reliable switching.
3
The compression molding properties of silicone
rubber is used to create angled webbing around a
switch center. When the switch is depressed, the
webbing deforms uniformly to produce a tactile
response.
4
After the pressure is removed from the switch,
the webbing returns to its original position with
positive feedback. A carbon or gold pill is
placed on the base of the switch center which
contacts onto a PCB when the web has been
deformed in order to make an electronic switch.
5
The tactile response and travel of a key can be
varied by changing the design of the webbing
and/or the shore hardness of the silicone base
material. The tactile forces are dependent on the
key size and shape and can be as high as 500g.
6
The tactile feel that is experienced is
determined by the snap ratio of a keypad. This
snap ratio for designers to maintain is
recommended to be between 40 and 60. If the
ratio dropped below 40 the keys will lose
tactile feel but have an increased life. When the
tactile feel is lost, there will not be a click
feedback received during actuation.

Polytech produces silicone keypad that can be
customized to different hardness and color
according to different requirements. Its
economical keypad can match the desired color and
is able to achieve varying forces and mechanical
movements. It can provide unique balance of
chemical and mechanical properties and also
sealing and protective capabilities. There is
also abrasion protection by PU coating.
