High quality conductive silicone buttons/switch buttons

Conductive silicone buttons need the underside contact region aligned with the intended circuit location. The visible top may fit a panel opening while the contact beneath it sits slightly off center, so both interfaces should be checked in the assembled switch. The locating features should hold that alignment without restricting the flexible movement of the button.

Define travel and the support below the part, including clearance when a user presses near an edge. Select the external shape and markings around the intended control function. Keep the conductive area clean during handling so assembly residue does not become part of the switching interface.

Test the completed switch with its actual electronics and housing fastening condition. Verify actuation and release through the range of presses relevant to normal use. If the button behaves inconsistently, inspect alignment, contact condition, and enclosure interference before replacing it. Avoid improvised conductive coatings or abrasive treatment, which can alter the contact geometry and material that the original switching arrangement was designed to use.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Define travel and the support below the part, including clearance when a user presses near an edge.

Custom dimensions

The visible top may fit a panel opening while the contact beneath it sits slightly off center, so both interfaces should be checked in the assembled switch.

Fit & assembly

Keep the conductive area clean during handling so assembly residue does not become part of the switching interface.

Use & inspection

If the button behaves inconsistently, inspect alignment, contact condition, and enclosure interference before replacing it.
