Conductive silicone keypads/silicone phone key buttons

Silicone phone key buttons should be evaluated in the way the finished phone is actually held. A press delivered while gripping the housing can differ from a straight press on a device resting flat on a bench. The housing, keypad support, and conductive contact arrangement need to maintain their intended relationship in those normal handling positions.

Define the key spacing and top shape around the expected finger access. Match the lower contact to its circuit location and keep enough clearance for release at each housing opening. Custom legends should remain visible at the working viewing angle.

Fit the keypad without residual stretch and test the assembled phone through relevant grips and presses. Check edge keys as well as central positions, and verify neighboring buttons remain inactive. During service, investigate housing flex or a displaced support if operation changes when the device is held differently. Preserve the selected button profile when replacing parts rather than adding material beneath a key to compensate for an unresolved support or alignment issue.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. A press delivered while gripping the housing can differ from a straight press on a device resting flat on a bench.

Custom dimensions

Match the lower contact to its circuit location and keep enough clearance for release at each housing opening.

Fit & assembly

Fit the keypad without residual stretch and test the assembled phone through relevant grips and presses.

Use & inspection

During service, investigate housing flex or a displaced support if operation changes when the device is held differently.
