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.

An electronic device includes a first plate spring, a second plate spring and a substrate. The first plate spring extends in a first direction from a fixed end. The second plate spring branches off from the first plate spring and extends in the first direction beyond a tip of the first plate spring in the first direction. The substrate has an electrode that contacts the second plate spring accompanied by the first plate spring being pushed by a pushbutton switch being pushed. The substrate does not contact the first plate spring. The second plate spring has a tip part. In a plan view in a push direction of the switch, the tip part extends, at a point beyond the tip of the first plate spring, in a second direction different from the first direction to overlap the substrate. The tip part contacts the electrode by the switch being pushed.

A switch assembly for an electronic device is described. The switch assembly includes a switch member, a housing and a support member. The housing is mounted on a printed circuit board and the switch member is attached to the housing. The support member is mounted on the surface of the printed circuit board adjacent to a back surface of the switch member.

The present invention provides a mobile terminal comprising: a terminal main body comprising a front case and an internal frame forming an internal area including an inundation area in which terminal water flows in and a waterproof area in which the inflow of water is blocked; and a key module mounted on the terminal main body and forming, by pressing, a control command, wherein the key module comprises: a first unit disposed in the inundation area and moved by an external force; a second unit disposed in the waterproof area and a signal generated by pressing; an elastic deformation layer having one region elastically deformed by movement of the first unit such that the second unit is pressed by the first unit; and a through hole, which allows the elastic deformation layer and the front case to be attached so as to partition the inundation area and the waterproof area and through which the first unit penetrates.

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 multiple function button for an information handling system includes an outer shell and an inner button. The outer shell includes multiple channels having first, second, third and fourth channels. The inner button is inserted within the outer shell. The inner button includes a tab and a contact component. The tab moves within the multiple channels. When the tab is within the first channel, the inner button is in a first position and contact component is positioned over a first contact of the information handling system. When the tab is within the third channel, the inner button is in a second position and the contact component is positioned over a second contact of the information handling system.

A push switch which can have a small separation distance from a side surface of a mounting board, when it is mounted on the mounting board through a step, is disclosed. The push switch includes a substrate having a first surface on which a first fixed contact point and a second fixed contact point surrounding the first fixed contact point are formed, a second surface located opposite to the first surface, a third surface extending from the second surface to a corner in a direction perpendicular to the first surface, and a fourth surface extending from the corner parallel to the first surface, and a conductive movable contact point having a peripheral edge is in contact with the second fixed contact point, and a center contacted by the first fixed contact point when the movable contact point is pressed, and the corner includes a groove recessed with respect to at least one of the third surface and the fourth surface.

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.

An electronic device includes an outer housing including a first surface, a second surface, and a side surface, a printed circuit board seated in the outer housing, and at least one side key coupled to a peripheral area of the outer housing. The side key includes at least one contact part exposed through a through-hole formed in the side surface of the outer housing, a side key circuit board including a switch module that contacts the contact part when the contact part is pressed, the side key circuit board being electrically connected to the printed circuit board, a side key bracket in which at least a portion of the side key circuit board is seated and which fixes and supports the side key circuit board, and one or more molded members that are coupled to opposite ends of the side key bracket and are coupled to the outer housing.

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.
