Conductive silicone rubber keypads/colored silicone buttons

Colored silicone buttons can be incorporated into a conductive keypad to distinguish individual controls or groups of functions. The visible color layout should be coordinated with the molded geometry and underside contacts from the start. This keeps appearance and electrical position aligned when the sheet is fitted into the equipment.

Define the housing openings, key travel, and locating features around the complete keypad. A change to a button's height or top shape should still preserve the movement available beneath it. Keep enough separation for neighboring buttons to remain released during a normal press.

Assemble without twisting or stretching the sheet and keep the conductive regions clean. Test the final control layout with the intended electronics, checking that each visible function corresponds to the correct input. During replacement, compare the complete version rather than choosing from color alone. A similarly colored keypad may have different contact spacing or support geometry, and forcing it into the housing can affect both alignment and the way its buttons return.

Material options

Silicone. Custom formulation and color for the intended contact conditions.

Hardness selection

Silicone: 20–80 Shore A. Keep enough separation for neighboring buttons to remain released during a normal press.

Custom dimensions

Define the housing openings, key travel, and locating features around the complete keypad.

Fit & assembly

A similarly colored keypad may have different contact spacing or support geometry, and forcing it into the housing can affect both alignment and the way its buttons return.

Use & inspection

Assemble without twisting or stretching the sheet and keep the conductive regions clean.
