KEY CAP STRUCTURE AND ELECTRONIC DEVICE THEREWITH

摘要

A key cap structure for disposing on a housing and corresponding to a circuit module is disclosed. The circuit module includes a circuit board and two contact portions disposed on the circuit board. The key cap structure comprises a top wall, a pair of side portions and a secure portion. The top wall has two press zones and a connect zone connects between the press zones. The press zones correspond to the contact portions respectively. The side portions connect to the press zones of the top wall respectively and extend downwardly and space apart from each other. The discontinuous structure between the side portions and the secure portion permits larger range of deformation formed in the top wall when the press zone is pressed downwardly. And the user only needs to apply less force to press on the top wall.
