An electronic device includes a housing including an opening, a key member disposed to project inwardly of the housing through the opening and, a switch disposed to face the key member, a first member disposed inside the housing, and a waterproof member disposed to surround the opening while being sandwiched between an inner surface of the housing and the first member. The first member includes a projecting portion that projects to be away from the opening and is contactable with the switch when the key member is pressed.

A computing device may include a housing with an aperture. A switch with an activation surface is connected to the housing. A button may be slidable within the aperture and may be configured to receive an activation force from a user to activate the switch. The button may be moveable to activate the switch. The button may have a back surface that is offset from the activation surface of the switch such that when the button is moved to the active position the activation surface and the back surface do not come into direct contact. An adapter may be positioned between the switch and the button, where the adapter has a switch surface and a button surface. The button surface may be aligned with the back surface of the button and the switch surface may be aligned with the activation surface of the switch.

An electronic device includes a housing having an opening, a key member including one or more pushers projecting inwardly of the housing, having one or more through-holes or one or more cutaway parts, and disposed to allow the one or more pushers to pass through the opening, one or more switches each disposed to face a corresponding one of the one or more pushers inside the housing, a first waterproof member disposed between each of the one or more pushers and each of the one or more switches, and one or more shaft members fixed to the housing. Each of the one or more shaft members enters the one or more through-holes or the one or more cutaway parts so as to limit part of a displacement of the key member relative to the housing.

Various embodiments relating to an electronic device including a key module are disclosed, and according to one embodiment, a portable electronic device comprises: a front glass cover defining the front surface of the electronic device; a rear cover defining the rear surface of the electronic device; a bezel surrounding a space defined by the front cover and the rear cover, the bezel being integrally formed with or separately formed from the rear cover, the bezel including a portion including an opening; a display device built in the space and including a screen area exposed through the front cover; and a plate including a plane parallel to the front cover within the space, wherein the opening penetrates from the outside of the bezel toward the space in a first direction. The electronic device comprises: a key having a size and a shape that can pass through the opening, the key being movably inserted in the opening and including a first surface facing the first direction; a support structure mounted on the plate or a portion of the bezel and including a hole through which the key passes; a dome button mounted on the support structure and arranged to face the first surface of the key and the hole so that the key can be pressed when moving in the first direction; and a waterproof structure including a flexible material. The waterproof structure may comprise: a first portion located between the first surface of the key and the dome button; and a second portion extending from the first portion and inserted between the support structure and the bezel, the second portion sealing a space between the support structure and the bezel so as to waterproof the space. Other various embodiments are also possible.

A keyboard switch for a keyboard includes a base secured to a plunger that reciprocates with respect to the base and is biased away from the base. An electrical contact assembly is positioned within a cavity defined by the base and the plunger. The electrical contact assembly remains in an electrically open state when the plunger is furthest from the base, but the electrical contact assembly enters an electrically closed state when the plunger is longitudinally moved downwardly by force towards the base. In this regard, a cam protruding from a side portion of a body of the plunger has a profile surface that contacts the electrical contact assembly as the plunger is longitudinally moved towards the base. A curved profile of the cam that incorporates a concave arc uniquely changes the amount of force experienced by the typist at different points of the downward motion of the plunger.

In a first aspect of the present disclosure, a spring plate includes a central portion; a first leg portion projecting outward from an edge of the central portion; and a second leg portion projecting outward from the edge of the central portion. The first leg portion includes a hollow portion that is positioned within an outline of the first leg portion in a top plan view, and the second leg portion includes a hollow portion that is positioned within an outline of the second leg portion in a top plan view.

A keyboard device includes a circuit board and plural key structures. Each key structure includes a keycap, a hinge element and a base. The hinge element includes a first lateral wing part, a second lateral wing part and a bendable part. The first lateral wing part is connected between the keycap and the base. The second lateral wing part is connected between the keycap and the base. The bendable part is connected between the first lateral wing part and the second lateral wing part. The bendable part is thinner than the first lateral wing part and the second lateral wing part. While the keycap is moved upwardly or downwardly relative to the base, a bending angle of the hinge element and a relative position between the first base shaft and the first receiving hole are changed.

An electronic device, according to one embodiment of the present invention, can comprise: a housing which has an opening part penetrating through the inside and the outside of the electronic device and forms the outside of the electronic device; a key button inserted into the opening part so as to be movable; a sealing member which is disposed such that the sealing member slidably contacts the outer surface of the key button, and prevents communication between the inside and the outside of the electronic device through the inner surface of the opening part and the outer surface of the key button; and a push switch accommodated in the housing and pressed by an inward movement of the key button. Various other embodiments are possible.

A switch assembly includes a manually operable push button, an elastic element, a rotatably mounted transmitter, and a microswitch, wherein the push button includes a pusher, which, upon actuation of the push button, exerts a first force on the elastic element, the elastic element connects to a force arm of the transmitter and is configured to transmit at least a part of the first force onto the force arm, and set the transmitter in a rotation, and the transmitter further includes a load arm configured to exert a second force on the microswitch during rotation of the transmitter.

The present description relates to devices, such as keyboards. One example can include a top portion and an opposing bottom portion and key switches that are mechanically retained in holes formed in the top cover. The example can also include electrical traces formed on the top cover that extend from the holes to a processing unit that is configured to receive electrical signals along the electrical traces when the key switches are closed.
