Abstract (en)
[origin: EP2355118A1] A dome overlay structure (1000,2000,3000) for a mobile device keyboard (810) includes a plurality of dome switches (100), a circuit board (105) disposed beneath the plurality of dome switches with each dome switch electrically coupled to the circuit board, a main overlay (110) disposed over the plurality of dome switches, and a first adhesive dab (115) centrally interposed between the dome switch and the main overlay with a second adhesive dab (125) surrounding the first adhesive dab. Each dome switch has a central portion (310) and a non-central portion (315). The first adhesive dab can bond the central portion of the dome switch to the main overlay. The second adhesive dab is configured to form a gap (325) between the second adhesive dab and the non-central portion of the dome switch in an unactuated configuration and configured to contact the non-central portion of the dome switch in an actuated configuration.
