Custom made silicone rubber button elastomer keypad

A silicone rubber button within an elastomer keypad should be developed with the common base that locates it in the device. The visible face and flexible support work together to provide the intended motion. Material hardness and molded dimensions need to be considered as a combination.

Check support around each operating region and the clearance through the housing opening. A large face may need different geometry from a smaller neighboring control even when both use the same silicone formulation. The mat should sit naturally without being stretched between locating features.

Evaluate the keypad after final enclosure assembly, including off-center touches and return from a held press. During fitting, keep the underside clean and inspect the edge for folds before tightening nearby hardware. Use the device's intended cleaning process for the exposed surface. If servicing requires removal, restore the same orientation and support relationship, then check the complete control set rather than relying only on the alignment of the most visible buttons.
