High quality elastic keypads/silicone push buttons/keystroke

Silicone push buttons use a flexible molded section to move between their resting and pressed positions. The intended keystroke depends on that geometry and the support provided by the enclosure. A button's elastic feel when held loose does not define its final travel or actuation force in the assembled control.

Check the head, wall and underside actuator as connected features. A wider head may change how an edge press loads the wall, while an incorrect board distance can leave too little or too much travel. The surrounding opening should guide the button without scraping its moving surface.

Evaluate the finished panel through complete presses and releases, including the normal finger approach. Keep neighboring keys independently operable where the layout requires it. During care, remove buildup around the openings without forcing sharp objects into the gap. If a key becomes uneven after servicing, inspect the locating and clamping surfaces so a trapped edge is corrected before the rubber is replaced or modified.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. A wider head may change how an edge press loads the wall, while an incorrect board distance can leave too little or too much travel.

Custom dimensions

Silicone push buttons use a flexible molded section to move between their resting and pressed positions.

Fit & assembly

A button's elastic feel when held loose does not define its final travel or actuation force in the assembled control.

Use & inspection

If a key becomes uneven after servicing, inspect the locating and clamping surfaces so a trapped edge is corrected before the rubber is replaced or modified.
