Conductive built-in silicone single buttons/rubber buttons

Conductive built-in silicone single buttons combine an individual flexible key with a contact area for a matching circuit arrangement. They can provide a compact physical input where only one command is needed at a particular panel location. The underside contact and its rest gap are central to the design.

When the key is released, the contact must separate as intended by the circuit. Too little clearance can leave the input active after assembly, while too much travel can make the button difficult to operate. Housing tolerances, board position and rubber deformation all contribute to the final gap.

Inspect the part's locating features before fitting so the conductive area faces the correct target. Test the finished assembly for both a clear press response and a complete release. Keep the contact face free of fingerprints, debris and cleaning residue during handling. A conductive button does not act as a general-purpose power switch; its electrical use must match the circuit's design and the selected contact arrangement.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Test the finished assembly for both a clear press response and a complete release.

Custom dimensions

Too little clearance can leave the input active after assembly, while too much travel can make the button difficult to operate.

Fit & assembly

Housing tolerances, board position and rubber deformation all contribute to the final gap.

Use & inspection

Keep the contact face free of fingerprints, debris and cleaning residue during handling.
