Custom conductive silicone buttons/waterproof silicone keypads

Waterproof silicone keypads require a complete panel construction that controls water paths around the moving buttons and the keypad perimeter. The molded part should provide its intended contact with the housing while preserving free button travel. Tightening the enclosure to improve perimeter compression can also affect key movement if the surrounding geometry is not coordinated.

Define the locating features, sealing path, and support beneath the sheet. Include any openings or hardware that pass through the control region. Conductive button areas need to align with the circuit while remaining protected within the intended assembled arrangement.

Install the keypad flat on clean mating surfaces and inspect for trapped edges before closing the housing. Test button movement after final fastening, then assess the completed enclosure under its relevant water exposure. A silicone component alone does not establish an enclosure protection rating.

For maintenance, inspect the perimeter as carefully as the individual keys. A small tear near a screw or a displaced corner can affect the barrier even when every button still operates. Keep cleaning methods appropriate to the completed control assembly, and preserve the designed compression when replacing the keypad rather than adding an extra layer beneath it to compensate for a damaged housing surface.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Tightening the enclosure to improve perimeter compression can also affect key movement if the surrounding geometry is not coordinated.

Custom dimensions

Define the locating features, sealing path, and support beneath the sheet.

Fit & assembly

Conductive button areas need to align with the circuit while remaining protected within the intended assembled arrangement.

Use & inspection

Install the keypad flat on clean mating surfaces and inspect for trapped edges before closing the housing.
