This rotationally operated electronic component, with which it is possible to obtain a fixed, high operating torque in both of two shafts, is provided with: a first block body which is disposed on one side in an axial direction, and which has a first hole; a second block body which is disposed on the other side in the axial direction, and which has a second hole; an outside operating shaft having a first cylindrical portion which fits into the first hole in such a way as to rotate about the axis; an inside operating shaft which extends in the axial direction, penetrates through the first cylindrical portion and the second hole, and fits into the first cylindrical portion in such a way as to rotate about the axis; a rotating body which is fitted onto the inside operating shaft in such a way as to rotate integrally with the inside operating shaft, and which has a second cylindrical portion that fits into the second hole in such a way as to rotate about the axis; a first radial direction resilient member which is sandwiched in a radial gap between the inner circumferential surface of the first hole and the outer circumferential surface of the first cylindrical portion while being flexed against a restoring force; and a second radial direction resilient member which is sandwiched in a radial gap between the inner circumferential surface of the second hole and the outer circumferential surface of the second cylindrical portion while being flexed against a restoring force.

A rotary transducer is described. The rotary transducer includes a Hall effect sensor, a rotary dial comprising at least two recessed pockets, a first magnet that is positioned within one of the at least two recessed pockets, and a second magnet that is positioned within another one of the at least two recessed pockets. In an acceleration only mode, the rotary dial is rotatable from a center position in a first direction and is not rotatable from the center position in a second direction. This mode is selected when a mode selection screw is inserted into a mode selection orifice. In a bi-directional acceleration/deceleration mode, the rotary dial is rotatable from the center position in the first direction and is rotatable from the center position in the second direction. This mode is selected when the mode selection screw is not inserted into the mode selection orifice.

Contact unit for a tap changer including a contact ring having a central axis, a plurality of fixed contacts arranged at a distance from the contact ring in different radial directions, and a moving contact arranged rotatable about the central axis of the contact ring and adapted to electrically connect the fixed contacts one at a time with the contact ring. The moving contact includes two elongated contact elements. Each of the contact elements includes a first contact area for providing electrical contact with the fixed contacts and a second contact area for providing electrical contact with the contact ring. The moving contact is designed so an electric path is formed between the first and second contact area. The first and second contact areas are positioned on opposite sides of a plane orthogonal to a longitudinal axis of the moving contact and including the central axis of the contact ring.

The present invention relates to a contact unit for changing over between winding taps on a control winding of a tapped transformer. Such a contact unit can be used particularly preferably for electrical switchgear in high-voltage engineering, such as selector switches or changeover switches. A common feature of both kinds of device in this case is that the changeover between the winding taps on the control winding of the tapped transformer is accomplished without load current. The general inventive concept is to include the contact element of the contact unit in a separate contact housing, so that the contact element and the contact housing form a separate assembly and so that the contact housing, including the contact element, can be fixed in a recess provided in the contact mounting by means of a retaining element.

A multi-directional operation switch that can be miniaturized is provided. The multi-directional operation switch includes an operation rod that is rotatable about an operation rod axis, and is also tiltable. The operation rod has an inner end portion inserted in a hole in a circuit substrate, and a slider, which operates in conjunction with an operation of the operation rod, is provided on the inner end portion. The slider has a movable contact. The circuit substrate has a plurality of fixed contacts that are brought into contact with, and are electrically connected to, the movable contact when the slider rotates or slides.

A rotational operation type switch includes a frame; a rotational operation button rotatably supported on the frame for rotational operation; a switching contact mechanism disposed below the operation button to face the operation button; and an operation mechanism disposed between the operation button and the switching contact mechanism, to switch the switching contact mechanism in conjunction with the rotational operation of the operation button. The switching contact mechanism includes a printed circuit board, a plurality of fixed contact electrodes disposed on the printed circuit board and spaced a predetermined distance away from each other, and a movable contact having a disc spring shape and disposed bridging between the plurality of fixed contact electrodes. The movable contact deforms to contact and separate from the fixed contact electrodes and switches an electrical connection between the fixed contact electrodes.

A haptic interface, including: a button which can be rotated by a user; an interaction element interacting with a magnetorheological fluid, secured to the button; a mechanism measuring a current position of the button; a brake including a magnetorheological fluid and a generation system to generate a magnetic field in the fluid; a controller configured to generate orders for the system to generate a magnetic fluid to modify a value of the magnetic field; and a mechanism to detect torque exerted by a user on the button to know direction of the torque and whether the torque is greater than a given value for a given direction, the controller controlling generation of a magnetic field based on obtained information about the torque at least when the button indicates zero or low speed.

A command selector includes a scroll wheel mounted in a support and free to rotate about a main axis, a fixed printed circuit board, a detection wheel rotating about a secondary axis, a means of transmission rotationally connecting the scroll wheel to the detection wheel of which the rotations are detected by a rotation sensor arranged on the printed circuit board. The main axis and the secondary axis are non-parallel, the means of transmission defines an angle, and the detection wheel rotating in a plane parallel to the printed circuit board, the secondary axis being perpendicular to the printed circuit board, so as to minimize the circumscribed volume of the selector.

A hair straightener and its integrated switch for control and display are disclosed. The hair straightener comprises first and second clamping plate parts and the integrated switch for control and display arranged on an inner side of the second clamping plate part. The integrated switch for control and display comprises a temperature control knob assembly for regulating and controlling temperature, a display button assembly for displaying the temperature and turning on or off a power supply, and a control motherboard for digital display and electrical control. The temperature control knob assembly and the display button assembly are installed on the control motherboard. The temperature display, control and regulation functions, and the power supply switching on and off functions are centralized on the same switch key, such that the temperature can be controlled and regulated conveniently when operated by one hand and the visual information can be obtained without obstacles.
