Rubber Keypads and Silicone Rubber Keypads

- Jun 11, 2018 -



A silicone rubber keypad is a better solution for some higher-volume applications that require raised, more responsive tactile feedback.  They are generally compression-molded and can be made with our without carbon conductive pads attached to the bottom of the keys. Typical designs feature a flex circuit or rigid PCB board as the base substrate of the assembly, and depending on complexity, MSK can also provide these sub-layers so there is no need to search for multiple suppliers to manufacture your complete keypad assembly.  Adding backlighting to the keypads is also possible so your device can function well in the dark. 



Engineered Technologies designs and manufactures all types and configurations of silicone rubber keypads for a wide range of industries and applications. For both large and small customers we provide engineering and design assistance to make sure that your keypads exceeds all of your specifications.

Silicone Rubber keypads are used extensively in both consumer and industrial electronic products as a low cost and reliable switching solution. The technology uses the compression molding properties of silicone rubber to which upon depression of the switch the webbing uniformly deforms to produce a tactile response. When pressure is removed from the switch the webbing returns to its neutral position with positive feedback.

In order to make an electronic switch a carbon or gold pill is placed on the base of the switch center which contacts onto a Printed Circuit Board when the web has been deformed.
