Custom conductive silicone keypads/Auto silicone buttons

Auto silicone buttons need to respond when reached from the hand positions used around the vehicle control panel. A driver or passenger may press a button from an angle, making side clearance and support beneath the key relevant to the design. The conductive contact should reach its intended circuit position without the top catching against the surrounding opening.

Coordinate key shape, travel, locating features, and the bezel dimensions. Consider the actual temperature and cleaning conditions at the installation. Custom colors or legends can distinguish functions, with their visibility checked once the panel is installed at its working angle.

Assemble the keypad without residual stretch and test it with the final electronics. Include off center presses and check that neighboring buttons remain released. During service, look for wear on one side of a key that may indicate repeated bezel contact. Correct the alignment or clearance as appropriate before fitting a replacement, so the next button does not start operating against the same interfering edge.
