An input mechanism is disclosed. The input mechanism includes a dome support structure defining an opening that extends through the dome support structure, a collapsible dome positioned in the opening and engaged with the dome support structure, and a cover member coupled to the dome support structure and covering the collapsible dome, thereby retaining the collapsible dome within the opening of the dome support structure.

A keyboard apparatus includes a base plate, a plurality of lifting mechanisms mounted to the base plate, and a plurality of keycaps. The keycaps are correspondingly mounted to the lifting mechanisms and are movable up and down relative to the base plate to form a pressing stroke. Each of the keycaps has a pressing surface, an assembly surface opposite to the pressing surface, and a plurality of connectors. The connectors are disposed on the assembly surface to be connected to the lifting mechanism, and a jig engagement portion protrudes from one side of at least one of the connectors. When the keycap is to be painted, the keycap is removably fixed to a painting jig by the jig engagement portion.

An electronic device may include a device housing having a topside and an underside. The electronic device may also include a mounting frame movable above the topside of the device housing and a finger biometric sensor carried by the mounting frame. A flexure member may be coupled to the underside of the device housing and configured to upwardly bias the mounting frame relative to the device housing. A pushbutton switch may be operatively coupled between the finger biometric sensor and the topside of the device housing.

A membrane switch and a method of manufacturing the same, includes upper and lower membranes printed with upper and lower conductive dots and an isolation layer between them, holes being opened in the isolation layer corresponding to the dots, the isolation layer is bonded with the upper and lower membranes respectively via the glue coated on the upper surface and the lower surface thereof; and the glue may employ hot melt glue. This method of manufacturing the membrane switch includes a coating the upper surface and/or lower surface of the isolation layer exclusive of the positions of the holes with glue; bonding and adhering the sides of the upper membrane and the lower membrane printed with the conductive dots and respectively to the upper surface and the lower surface of the isolation layer via glue, making the positions of the conductive dots and the holes corresponding to each other.

A thin keyboard device is described herein. In one or more implementations, a keyboard device includes a plurality of keys, and a housing that includes a structural printed circuit board (PCB). The structural PCB includes, for each of the plurality of keys, a first conductive trace and a second conductive trace. The keyboard device further includes a key-switch mechanism for each of the plurality of keys. The key-switch mechanism includes a conductive material oriented towards the first conductive trace and the second conductive trace, and is configured to cause the conductive material to move downwards, when the key is depressed, to electrically connect the first conductive trace and the second conductive trace of the depressed key.

An electronic device may include a device housing having a topside and an underside. The electronic device may also include a mounting frame movable above the topside of the device housing and a finger biometric sensor carried by the mounting frame. A flexure member may be coupled to the underside of the device housing and configured to upwardly bias the mounting frame relative to the device housing. A pushbutton switch may be operatively coupled between the finger biometric sensor and the topside of the device housing.

A slim-type keyboard includes a first flexible layer, a pressed frame and a circuit board assembly. The first flexible layer includes plural pressed regions. The pressed frame includes plural cantilever strips. The circuit board assembly includes plural dome switches. The plural cantilever strips are covered by the first flexible layer. The pressed regions are aligned with the cantilever strips and the dome switches, respectively. When one of the pressed regions is pressed, the cantilever strip is pushed down to trigger the corresponding dome switch. Each cantilever strip includes a U-shaped groove and a suspension end. The U-shaped groove opens to the suspension end. Consequently, the tactile feel of pressing the cantilever strip is improved.

The present disclosure provides a keycap and a keyboard apparatus. The keyboard apparatus includes a base plate, a plurality of lifting mechanisms mounted to the base plate, and a plurality of keycaps. The keycaps are correspondingly mounted to the lifting mechanisms and are movable up and down relative to the base plate to form a pressing stroke. Each of the keycaps comprises a pressing surface, an assembly surface opposite to the pressing surface, and a plurality of connectors. The connectors are disposed on the assembly surface to be connected to the lifting mechanism, wherein a jig engagement portion protrudes from one side of at least one of the connectors; when the keycap is to be painted, the keycap is removably fixed to a painting jig by the jig engagement portion.
