A push switch including a pressing member, a movable contact, an interposed member, a first fixed contact, and a second fixed contact is provided. The pressing member includes a pressing portion configured to be pressed, and includes an elastically deformable peripheral wall portion having a lower end portion and extending downward and outward from the outer periphery of the pressing portion. The movable contact has a dome shape and is disposed below the pressing member. The interposed member is disposed between the pressing member and the movable contact, and is configured to press the movable contact by receiving and being pressed by the lower end portion of the peripheral wall portion of the pressing member. The lower end portion of the peripheral wall portion of the pressing member presses the interposed member while the peripheral wall portion is subjected to elastic deformation in response to the pressing portion being pressed.

A switch device includes a substrate having at least one fixed contact and an inflow/outflow section provided with at least one through-hole, and a rubber contact to cover the substrate. The rubber contact includes at least one moving section disposed facing the respective at least one fixed contact, the moving section elastically deforming such that moving contacts corresponding to the respective fixed contacts are capable of contacting/separating, an in/out section disposed facing the inflow/outflow section and configured to form a space with the inflow/outflow section, a flow path section configured to form a flow path to connect the in/out section and the at least one moving section, and at least one chamber section having a space larger than a space occupying along representative length of the flow path section on a portion of the flow path section, and having strength such that a shape of the space is maintained.

A key device includes a substrate, a key cap and a restoring member. The substrate includes a top surface and two pivot seats protruding on the top surface. The pivot seats are spaced from each other. Each pivot seat has an eave portion laterally extending from a top thereof. The eave portion has a bottom edge. The key cap is above the top surface. The key cap includes a side edge and two extending arms extending from the side edge. An end of each extending arm has a pivoting portion. The pivoting portions pivotally abut against the bottom edges of the eave portions respectively without contacting the top surface of the substrate. The restoring member is between the substrate and the key cap and abuts against a bottom of the key cap.

Systems and methods for a hack-proof security keyboard are described. In some embodiments, a keyboard module may include a first circuit configured to detect activation of a plurality of keys and a second circuit configured to detect activation of a subset of the plurality of keys, where the second circuit overlies the first circuit. In other embodiments, a method may include detecting an electrical signal received from a secondary membrane of a keyboard, where the keyboard includes a primary membrane configured to detect individual activation of any of a plurality of keys, and where the secondary membrane is configured to output the electrical signal in response to concurrent activation of a subset of the plurality of keys. The method may also include performing a selected action in response to the detection.

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.

The present disclosure relates to a switch assembly for a motor vehicle component, including: an electronic basic body for arranging a contact member; an actuating member for actuating the contact member; a web associated with the actuating member, including a web portion with a web stop; a flexible switching mat having a basic portion for arranging the actuating member and the web; an operating member having an operating portion with an operating stop and an operating counter-stop disposed opposite to the web stop; a support member connected to the basic body or the switching mat having a support portion with a support counter-stop that contacts the operating stop in a non-actuated state of the switch assembly; wherein the web provided on the basic portion is arranged to be spaced apart from the actuating member provided on the basic portion, wherein the web encloses the actuating member at least partially.

Key assemblies having a foldable stabilizer are disclosed. The stabilizer can be positioned under a keycap to help guide the keycap and limit rotation or movement when the key is pressed. The stabilizer can have a pointed-star shape with multiple folding axes and can have multiple points of connection or linkage to the keycap or other surrounding components. The stabilizer can unfold or flatten as the keycap is pressed and can fold as the keycap is raised.

A key device includes a substrate, a key cap and a restoring member. The substrate includes a top surface and two pivot seats protruding on the top surface. The pivot seats are spaced from each other. Each pivot seat has an eave portion laterally extending from a top thereof. The eave portion has a bottom edge. The key cap is above the top surface. The key cap includes a side edge and two extending arms extending from the side edge. An end of each extending arm has a pivoting portion. The pivoting portions pivotally abut against the bottom edges of the eave portions respectively without contacting the top surface of the substrate. The restoring member is between the substrate and the key cap and abuts against a bottom of the key cap.

Provided are an input device and an electronic apparatus each including capacitive elements and being capable of allowing a plurality of information items to be separately input by simple operations. The input device includes: a capacitive element; a conductor that can be electrostatically coupled to the capacitive element; an operation portion that allows a load to be applied to the conductor; and a retaining portion that retains the conductor apart from the capacitive element. The retaining portion is capable of displacing the conductor with respect to the capacitive element in a stepwise manner in accordance with the load that is applied to the conductor through intermediation of the operation portion, and is capable of retaining the conductor at a plurality of positions with respect to the capacitive element.

A reaction force generating member includes: a first dome that gives a reaction force to an operation member according to the depression of the operation member; and a second dome that includes a hemispherical bowl part disposed inside the first dome, and a projection projecting downward from the center of the bowl part and depressing a switch disposed below the operation member.
