Keyboard dome overlay structure

A dome overlay assembly for a keyboard configured to influence tactile response of the keyboard, the dome overlay comprising:

• at least one dome switch comprising a central portion and a non-central portion, the at least one dome switch corresponding to at least one key of the keyboard;
• a circuit board disposed beneath the at least one dome switch and being electrically coupled to the at least one dome switch, a main overlay disposed over the at least one dome switch;
• a first adhesive dab having a first thickness interposed between the main overlay and the central portion of the at least one dome switch, wherein the adhesive dab bonds at least the center of the at least one dome switch to the main overlay;
• and
• a second adhesive dab having a second thickness applied to at least a portion of a surrounding region about the first adhesive dab on the main overlay to thereby at least surround more than half a perimeter defining the first adhesive dab, wherein the second thickness is less than the first thickness and whereby a gap is formed between the second adhesive dab and the non-central portion of the at least one dome switch in an unactuated configuration, and the second adhesive dab is configured to contact the non-central portion of the at least one dome switch in an actuated configuration thereby influencing the tactile response of the keyboard.
