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.

An input key assembly including: a keycap; a substrate; an elastic deformable shell-like structure disposed between the substrate and the keycap; and an optical sensing arrangement disposed on the substrate to transmit a light beam and sense an interruption to the light beam. The elastic deformable shell-like structure includes a peripheral base portion in abutment with the substrate; an apex portion in abutment with the keycap; and a plunger-like element extending away from underneath the apex portion, wherein a free-end of the plunger-like element is opaque. The elastic deformable shell-like structure and the optical sensing arrangement are arranged in a manner such that the free-end of the plunger-like element interrupts the light beam when the keycap is depressed to deform the elastic deformable shell-like structure for collapsing the apex portion relative to the peripheral base portion to move the plunger-like element along a longitudinal axis of the plunger-like element.

A base element and at least one switching element are included in an operator control device which may be disposed in a vehicle. By closing at least one electrical contact, the switching element is moveable from a first position into a second position relative to the base element. The operator control device can also include at least one pushbutton switch moveable relative to the base element between a position of rest and at least one activation position. The operator control device can further include at least one restoring element, formed of silicone and supported on the base element and on the pushbutton switch, which can be elastically deformed by moving the pushbutton switch from the position of rest into the activation position. Using the restoring element, the pushbutton switch can be moved from the activation position into the position of rest by relaxing the restoring element.

A switch device includes a circuit board, a coil structure, a lower cover, an upper cover, an elastic part, and a sliding part. The circuit board gas a through hole running through the circuit board. The coil structure is disposed on the circuit board and surrounds the through hole. The lower cover us located over the coil structure. The upper cover is disposed on the lower cover. The lower cover and the upper cover form an accommodating space. The elastic part is located in the accommodating space. The sliding part passes through an opening of the upper cover and is configured to slide relative to the lower cover along a direction. The sliding body is configured to drive the sliding part to pass through the through hole along the direction to generate a switch signal corresponding to an inductance variance of the coil structure.

Disclosed are a button structure and an electronic device. The button structure may be mounted on an outer shell. The button structure may comprise: a button cover having a display pattern; and a soft rubber comprising a deformation part and a connection part. The deformation part is connected to an inner surface of the button cap, and the connection part is configured to connect to an inner wall of the outer shell. The button structure may further comprise a circuit board comprising a light source and a button. Light emitted by the light source can be emitted through the display pattern.
