compressed mold rubber silicone keystroke and switch buttons

A custom rubber silicone keystroke component forms the flexible key used in a switch assembly. Compression molding can develop the shape around the panel opening and the internal pressing point. The key should move in the direction required by the switch without catching on the surrounding enclosure.

Review the relationship between the exposed face and the support beneath it. If they are offset, a press may tilt the key and bring one side against the opening. The molded geometry and locating features should keep the intended load path aligned. Test the assembled key with presses made at normal finger positions, including those slightly away from the center.

Different sizes, colors, and shapes are available for customization. The selected compound should suit the actual control environment. During fitting, avoid trapping a thin edge beneath the panel. Check release after the enclosure is fully secured, since a key can appear free before the final housing compression changes its position and movement clearance.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Check release after the enclosure is fully secured, since a key can appear free before the final housing compression changes its position and movement clearance.
