A selection controller for manual selection of an operating mode and/or operating characteristics of an audio control device is disposed within an interior of a vehicle. The selection controller includes a selector element that is designed to allow a user to make the manual selection. The selecting element can be arranged at least in a first position that is not elevated from a control surface of the audio control device and in a second position that is elevated from the control surface of the audio control device.

A knob assembly includes a first housing with a sidewall extending from a base and a retention member inwardly extends from the sidewall. An operable second housing includes a selective stopper selectively movable between a first position and a second position relative to the retention member. The operable second housing is further axially operable between a compressed position and an extended position relative to the first housing, and the operable second housing includes a biasing member.

Proposed is an operation apparatus for a vehicle that improves visibility and interior aesthetics by appearing/disappearing mechanism of a button. The operation apparatus includes a panel, an operation module capable of moving, through an opening of the panel, between a first position and a second position spaced apart from each other in a front-back direction, a button placed on the operation module, a rotary link rotatably provided on an axis orthogonal to the front-back direction, a drive source for rotating the rotary link, and a cam mechanism having a guide path for inducing an angular motion of the rotary link and, thereby, moving the operation module to the first position or the second position.

Provided are an operating assembly and a household appliance. The operating assembly includes a first operating portion and a second operating portion. The first operating portion is at least partially disposed in the second operating portion. The second operating portion can be located at and move back and forth between a first position and a second position of the first operating portion. When the second operating portion is located at the first position, the second operating portion can rotate relative to the first operating portion to generate a first electric signal; when the second operating portion is located at the second position, the second operating portion can drive the first operating portion to rotate to generate a second electrical signal during the rotation of the first operating portion; and the first operating portion can be pressed to generate a third electric signal.

A knob structure for an electromagnetic oven includes a knob switch assembly. The knob switch assembly consists of a sleeve button, a rotary encoder, a bracket of a display screen, and a control assembly. The knob switch assembly is connected to a printed circuit board through a through hole. A guide rib is disposed around a circumference of the through hole. The display screen with a protection assembly disposed outside is integrated with the knob switch assembly. The guide rib effectively prevents water from entering inside of the electromagnetic oven, lengthens a service life of the electromagnetic oven, and facilitates cleaning. The knob switch assembly integrated with the display screen realizes miniaturization and reduces a cost. The protection assembly ensures a display effect of the display screen.

An input apparatus for a vehicle includes: a knob rotatably disposed in a plate; a driving device allowing the knob to protrude from or move downward into the plate; and a switching mechanism movable disposed to surround an outer circumferential surface of the knob protruding from the plate and disposed along a circumference of the knob moved downward into the plate.

The present invention relates to a cooling device (1) comprising at least one compartment (2) wherein foodstuffs desired to be cooled are placed, at least one door (3) providing access into the compartment (2) and a push-release type knob (4) that is situated on the surface, facing the inner volume of the compartment (2), of one of the compartment (2) walls, that enables the compartment (2) temperature (T) to be changed by the user and that has an active position wherein the temperature adjustment is performed by rotating the knob (4) and a passive position to which the knob (4) is changed by being pushed when the desired temperature value is set.
