Input Device Securing Techniques

An input device comprising:

• a sensor substrate having a first set of one or more conductors of a first key and a second set of one or more conductors of a second key;
• a spacer layer disposed proximal to the sensor substrate and having first and second openings that expose the first and second sets of conductors, respectively;
• and
• a flexible contact layer spaced apart from the sensor substrate by the spacer layer and configured to flex through the first and second openings responsive to an applied pressure to initiate respective first and second inputs, in which flexibility at locations of the first key is different than flexibility at corresponding locations of the second key through arrangement of discrete portions of applied adhesive that secures the flexible contact layer to the spacer layer along one or more edges of the respective first and second keys.

A keyboard device comprising:

• a sensor substrate having a first set of one or more conductors of a first key of the keyboard and a second set of one or more conductors of a second key of the keyboard;
• a spacer layer disposed proximal to the sensor substrate and having first and second openings that expose the first and second sets of conductors, respectively;
• and
• a flexible contact layer spaced apart from the sensor substrate by the spacer layer and configured to flex through the first and second openings responsive to an applied pressure to initiate respective first and second inputs.
