Factory custom molded silicone buttons silicone rubber keypads

Molded silicone buttons provide flexible operating surfaces for a custom keypad. Their dimensions can follow the housing openings and the switch layout, with the visible cap and supporting rubber developed as one component. The external shape should remain usable after the panel covers its surrounding edge.

Check the amount of face area available for a finger and the clearance around the cap. A tall button needs room to move without rubbing sideways, while a low button must remain accessible from the normal operating direction. The underside needs to correspond to the intended switch position and travel.

Fit the keypad on its supports and inspect the edges before tightening the enclosure. Test the controls after the case is secured, looking for incomplete return or interference from neighboring keys. Keep the underside clean during assembly. Select the compound for the actual operating and cleaning conditions, and inspect the seating if the button feel changes after service. A small change in case or board position can influence the movement of the molded control.
