In a rotating operation body, a cam part has first cam faces for click feeling generation and second cam faces for return of the rotating operation body. The second cam faces are respectively formed continuously with the first cam faces, and an angle between each of the second cam faces and a direction in which elastic forces of engagement parts are generated is smaller than an angle of each of the first cam faces. That is, each of the second cam faces has a steeper slope than each of the first cam faces.

A control device intended for a user to choose and select functions in a vehicle includes a knob that can be manipulated in rotation about a main axis with respect to a fixed support. The knob comprises a neutral position in which the main axis coincides with a neutral axis that is fixed with respect to the support. The control device also comprises a printed circuit board on which the knob and at least one direction sensor are fixed. The printed circuit board is mounted with the ability to pivot with respect to the support about an axis transverse overall to the neutral axis so as to come to occupy at least a first activated position in which the main axis is inclined with respect to the neutral axis when the knob is moved in a direction orthogonal to the neutral axis. The direction sensor is intended to detect the activated position.

A device for connection to an input device actuated by a user comprises: a driving member for connection to the input device; a follower member; wherein motion of the driving member is only transmitted to the follower member after the driving member has been moved by a certain amount; and wherein means are provided to transmit a force back to the user as the driving member is moved in one direction.

A mechanism to prevent an adjustment knob associated with a piece of equipment (e.g. musical instrument or amplifier) from being moved accidentally includes an inner hub held in place on an adjustable shaft. An knob body fits concentrically over the inner hub, and is biased into position over the hub. The bottom of the knob body has locking structure which lockingly but releasingly cooperates with locking structure associated with the piece of equipment to which the shaft is affixed. A biasing structure such as a spring retains the knob body in a first, locked, position, in which the knob body is prevented from rotating, which in turn prevents rotation of the adjustable shaft. However, when the knob body is pulled away from the locking structure against the spring force, the knob body can be rotated, which in turn rotates the hub and shaft shaft. Releasing the knob body allows the biasing structure to urge the knob body back into engagement with the locking structure.

A system for a two-step activation for a valve includes at least one valve control selector having an output representative of a valve position and a touch sensor having an output representative of a permission to operate said valve.

A tiller knob has a top section having a lower periphery with a first plurality of indented segments and a bottom section having an upper periphery with a second plurality of indented segments. When the lower periphery and the upper periphery are mated with one another, the first plurality of indented segments cooperates with the second plurality of indented segments to form separate openings around an outer circumference of the tiller knob. A center section is located between the top section and the bottom section so that outer surfaces of extending segments are exposed through the separate openings. A multi-sectional tiller knob having top and bottom sections formed of a first material and a center section formed of a second material is also disclosed.

The present disclosure provides a device for selecting a desired switch position out of a plurality of switch positions, and a switch position depends on a position of at least one locking bolt relative to a snap-in cam, with a support member for a control element. The support member is arranged below a user interface and rotatable around a shaft relative to the locking bolt. The snap-in cam is designed in the support member, and a Maltese cross transmission structure is formed in the support member. A drive device is in engagement with the Maltese cross transmission structure so as to rotate the support member with the snap-in cam around the shaft relative to the locking bolt depending on the desired switch position.
