costom Silicone Rubber Keypad membrane switch with 3M adhesive
There is a wide range of actuation forces for keypads in different
use. According to the difference, silicone keypads are also applied
in the following areas.
The actuation force is about 50-80g, which is generally suitable
for use in computer keyboards and calculator keys. The pressing
force in this range is not high; it is easy to press and has a
light tactile feel. It is suitable for rubber keypads that need to
be clicked frequently.
The pressing pressure is about 80-120g, which is generally suitable
for electrical buttons and remote controls. Its force is suitable,
the hand feels comfortable, and the resilience is great.
If the actuation force is 120-180g, it is generally suitable for
consumer and industrial electronic products. For example, keypad
designed for sound equipment, industrial instruments, and
mechanical remote controls. Its pressing force is much larger than
that of the second type, and it is generally suitable for
relatively large silicone keypads. Its resilience is also superior,
but not suitable for products with frequent clicks.
The pressing pressure is more than 180g. In general, this type of
pressing rubber keypad is relatively rare. It should be designed
and manufactured for special industries, such as medical, aviation,
and other industries. It needs frequent use of fingers for a short
time, which makes it more acidic.
