Rubber keypad Membrane Switches = Rubber Keypad + Membrane Switch
Silicone Rubber keypad Switches are excellent choice for device
operation controls. It is soft and elastic. It can give user a very
nice touch feeling. In addition rubber is also have the following
features and benefits:
- Excellent resistance to both heat and low temperature (-55℃ to
- Minimum noise generation due to soft and elastic contact structure
- Minimum abrasion and high resistance to SO2 and oxidation even in
- Water and contamination resistant
Cosmetically appealing, 3-D Rubber Keypads offer the reliability of
a membrane or PCB-substrate switch, with the three-dimensional look
and tactile feel of a silicone rubber keypad for a variety of
applications including medical, industrial, and commercial
Why need rubber keypad switches?
As we know the common membrane switch is usually use PET and PC
film as the graphic overlay. The product can be very thin, usually
less than 1mm. But sometimes many customers design their product to
be rubber keypad switches. Because of that rubber can give users a
very good touch feeling. In addition, rubber keypads can make
carbon pills on the backside of the buttons, the carbon pills are
conductive, then it can be combined with PCB circuit very easily.
We only need make the gold plated conductive pads on the PCB, then
assemble the rubber keypad with PCB, when you press the buttons,
the carbon pills will connected to the gold pads, then trigger
The rubber keypad switches also can achieve the backlighting
easily. As we know the rubber raw material usually is translucent.
It is light through. After painted we wanted colors on the rubber,
we only need laser etch the backlit symbols and letters, then the
LED light from the backside of PCB or membrane circuit can be
through the etched area out to get the backlit effect.
Rubber is easy to clean, so once the keypad is contaminated you can
clean it very easily. Rubber keypad's press life also is very high.
At least 1, 000, 000 times above. It is very durable and not easy
damaged. So the rubber keypad switches are widely used in
machinery, industrial manufacturing, vending machine, dirty and oil
contamination environment and others.
