A switch including a housing and an actuator configured to move axially within the housing. The actuator includes a guide wing on a first side and a cam wing on a second side, wherein the cam wing has a cam surface on one face. The switch also includes respective first and second contact terminals partially extending from the housing, as well as a movable contact element retained within the housing proximate the contact terminals. The movable contact element includes a fixed branch, a first elastically deformable conductive blade, and a second elastically deformable conductive blade. The cam surface on the actuator is configured to cooperate with the first elastically deformable conductive blade to deform or relax the first elastically deformable conductive blade so as to selectively contact the first contact terminal dependent upon the axial position of the cam wing within the housing.

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.

A method of assembling a surgical instrument includes coupling a power bus to a switch base that has a top, a bottom, and side surfaces; adhering a membrane to the top surface of the switch base over the power bus to form a switch base assembly; positioning the switch base assembly within a first portion of a switch base cavity defined by a lower housing portion; and joining the lower housing portion with an upper housing portion. The upper housing portion defines a second portion of the switch base cavity. Joining the lower housing portion with the upper housing portion disposes the switch base within the first portion of the switch base cavity and prevents fluid from penetrating a proximal portion of the switch base cavity within which an electrical lead is coupled to the power bus.

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.
