A signal input module includes: a key body; a key base coupled to a lower portion of the key body, and having fixing portions of different heights at both sides thereof; a flexible printed circuit board disposed such that an upper surface thereof is covered by the key base, and having a dome portion on a rear surface thereof, the dome portion configured to generate a signal when pressed by the key base; and a light emitting portion formed on one surface of the flexible printed circuit board, wherein the fixing portion and the key base are connected to each other by a connection portion, wherein the connection portion is bent from one end of the key base, extends toward the fixing portion, wherein the connection portion is provided with a hole, and wherein the flexible printed circuit board is disposed to cross the hole. Under such configuration, the number of components can be reduced and the signal input module can have a slim configuration.

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 key switch including: a support base; a key which is manually operable for being moved, with respect to the support base, between at least a first operating position and a second operating position spaced apart from each other, in order to establish or interrupt at least one electric connection; a leaf spring member operatively interposed between the support base and the key; wherein the first operating position is a stable operating position of the key in which the leaf spring member is deformed between the key and the support base so as to take a first curvilinear configuration.

A key structure is provided, including a key housing, a keycap, an elastic piece and a spring. The key housing comprises an interfering portion. The keycap is movably assembled to the key housing along a pressing axial direction. The elastic piece is movably assembled to the keycap along the pressing axial direction. The elastic piece comprises a protrusion, and the interfering portion is located on a movement path of the protrusion. The spring abuts between the keycap and the elastic piece. When in an initial position, the protrusion is stopped at the interfering portion. When an external force is applied to the keycap, in a pressing process, the keycap is moved relative to the key housing, and drives the protrusion to surmount and cross over the interfering portion. An elastic restoring force of the elastic piece causes the protrusion to hit the interfering portion to make a sound.

An electrical control mechanism having a support. A central body that is movable in rotation about a central axis of rotation (AXROTC) carries a button that is movable in rotation relative to the central body about an offset axis of rotation (AXROTD) parallel to the central axis of rotation (AXROTC). First return means are interposed between the central body and the button, with second return means being interposed between the central body and the support. Two primary electric switches are interposed between the button and the central body on either side of a plane containing the central axis of rotation (AXROTC) and the offset axis of rotation (AXROTD). Two secondary electric switches are interposed between the support and the central body on either side of the plane.

A travel switch with a high-safety lever structure comprises a travel adjustment device, a transmission device, a lever-structure electric-connection switch assembly, an insulation assembly and a rivet fixing assembly; the switch assembly comprises a dual-energy-storage-reed structure and a stationary contact piece; the dual-energy-storage-reed structure comprises a stationary reed and a moving reed; the moving reed and the stationary reed are spaced apart at one end, and the moving reed is connected to the stationary reed at another end; the moving reed has energy storage reeds and a moving contact; the stationary reed has energy storage reed positioning hooks; the energy storage reed hooks the energy storage reed positioning hook in a matched mode; the stationary contact piece has a stationary contact; a moving contact limiting block is on the stationary reed; the moving contact connects the stationary contact, and the moving contact corresponds to the moving contact limiting block.

An operating assembly unit for a motor vehicle may include a switch for shifting speed levels of an automatic motor vehicle transmission. The switch may include a first lever that is manually operable, a second lever mechanically coupled to the first lever, and a switching element. The first lever may be movable to actuate the electrical switching element by causing contact between the electrical switching element and the second lever. The second lever may include a leaf spring with a clamped end and a free end. The actuation of the first lever may deform the leaf spring such that at least a portion of the leaf spring is displaced towards the switching element.
