Silicone Rubber Keypads
Epec 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.
Rubber Keypad Design
Rubber keypads can be designed so that they achieve a positive tactile response when the operator depresses the keypad.
To achieve good tactile feel that is inherent in the rubber keypad the keypad should have at least .060" of travel and should have an actuation force of between 50 and 170 grams.
As an alternative, a tactile layer can be incorporated in between the rubber keypad and the circuitry layer, which will enable a good tactile feel even with small keys and minimal travel distances.
