An electronic device including a button assembly is provided. The electronic device includes a housing, a button member which is at least partially exposed to the outside of the housing, a substrate portion disposed in an inner space of the housing, a dome switch module mounted on the substrate portion, a bracket mounted inside the housing, and a block member which is disposed between the dome switch module and the bracket and includes a base portion coupled to one surface of the bracket, a contact portion in contact with the dome switch module, and a support portion disposed on the periphery the contact portion.

A keyboard device includes a substrate, keycaps, and a frame. The substrate has a top surface and a bottom surface and includes a welding-fixing portion. The welding-fixing portion includes a through hole and an arch-shaped bridge member. The arch-shaped bridge member is connected in the through hole and divides the through hole into partition holes. The arch-shaped bridge member has an arch portion and bridge bases. The arch portion protrudes from the top surface to form a recessed portion. The frame is disposed on the top surface and includes hollow holes respectively corresponding to the keycaps. The frame includes a welding member, and the welding member includes welding posts and a welding-fixing base. The welding posts respectively pass through spaces between the edge portion of the through hole and the arch-shaped bridge member. The welding-fixing base is received and fixed in the through hole and the recessed portion.

Pressure sensitive key techniques are described. In one or more implementations, a device includes at least one pressure sensitive key having a flexible contact layer spaced apart from a sensor substrate by a spacer layer, the flexible contact layer configured to flex responsive to pressure to contact the sensor substrate to initiate an input, for a computing device, associated with the pressure sensitive key. At least one of the flexible contact layer or the sensor substrate are configured to at least partially normalize an output resulting from pressure applied at a first location of the flexible contact layer with an output resulting from pressure applied at a second location of the flexible contact layer that has lesser flexibility than the first location.

A push-button switch member includes: a movable contact and an operation key disposed facing the protruding side thereof, and in contact therewith or spaced therefrom. The movable contact includes: an upper contact portion disposed directly under a key body; an outer fixed portion in the upper contact portion or more outward therefrom in the radial direction, and fixed more outward in the radial direction than the key body; and a non-contacting outer portion provided more outward in the radial direction than the upper contact portion, and disposed to face in a non-contacting state another contact so as to be able to contact another contact which is disposed on an outer side in the radial direction and contacted by the upper contact portion when pushed by the key body. The non-contacting outer portion has a bottom portion for a line contact or a surface contact with another contact.
