An electric arc extinction chamber comprises a stack of electric arc splitter plates. The splitter plates define an inlet of the extinction chamber that is to be present facing electric contacts, and a back of the extinction chamber. At least one permanent magnet is present inside the extinction chamber in a central zone in the width direction of the extinction chamber and beside the back thereof. The magnet presents magnetization having a non-zero component along an axis extending between the inlet and the back of the extinction chamber.

A longitudinal switch for an electric contact locking and position changing system was designed to position securely the movable switch elements (7), which are urged by springs (5) and a rack (1) and toothed gear (8) mechanism for moving a vertical shaft (9), acting upon fixed elements (contacts) (16) of an electrically insulating rail surface (15). Positions are changed by turning a control button (39) and the toothed gear (8), causing the vertical shaft (9) to rotate, thus moving the rack (1) and causing the movable elements (7) to slide on the semicircular surface (17) of the fixed elements (16), overcoming the force of the springs (5) and compressing them. Once the gap between the fixed elements (16) is located, the springs (5) push back, keeping the movable elements (7) locked and ensuring the effective electric contact with the electric current passing through these points of contact.

An input operation device according to the present disclosure includes first to third light-emitting sections, a first light guide body, and a second light guide body. A lower end of the first light guide body faces the first light-emitting section and the second light-emitting section. The first mark emits light on the first light guide body when light is incident on the first light guide body from the first light-emitting section, and the second mark emits light on the first light guide body when light is incident on the first light guide body from the second light-emitting section. The upper surface section of the second light guide body emits light when light is incident on the second light guide body from the third light-emitting section. At least one of the first light-emitting section, the second light-emitting section, and the third light-emitting section can change light emission luminance.

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 control knob for an appliance includes a base having an axially-operated switch. An outer control assembly is rotationally and axially operable with respect to the base. An inner display assembly is rotationally fixed with respect to the base and axially fixed with respect to the outer control assembly. The inner display assembly is biased toward an extended state and is axially operable to a selection state that engages the axially operated switch.
