An operating device for a steering wheel comprises an operating element, which can be selectively rotated about a first rotation axis and a second rotation axis for controlling a control system by means of an actuation, wherein the operating element can be rotated to an actuation stage from a starting position, wherein the first rotation axis is coaxial to the longitudinal axis of the operating element, and the second rotation axis is substantially transverse to the first rotation axis, wherein a force application point has a mechanical advantage with respect to the second rotation axis when actuated about the second rotation axis, and wherein the force application point has no substantial mechanical advantage in relation to the second rotation axis when the operating element is actuated about the first rotation axis, in order to prevent a simultaneous actuation of the operating element about the first and second rotation axes.

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.

An operation knob apparatus includes a base a conductive transmitting member, an operation member that brings the transmitting member near to and away from a display panel, and a stabilizer disposed between the bases and the operation member. The stabilizer includes a main body, a pair of arms connected to respective ends of the main body, and a pair of base portions and connected to the respective arms. One of the base and the operation member has a holding portion configured to rotatably hold the main body, and the other has a pair of holding grooves respectively configured to slidably and rotatably hold the base portions.

In certain embodiments, an electronic input device includes a knob assembly defining an annular cavity and including a magnetically attractable armature. The electronic input device also includes a ratchet assembly disposed within the annular cavity and includes a ring magnet. The electronic input device includes a clutch mechanism that has a friction disc assembly, and an electromagnet configured to generate a magnetic field that shifts the friction disc assembly between a first position in which the friction disc assembly prevents rotation of the ratchet assembly and a second position in which the ratchet assembly is free to rotate with the knob assembly. The ring magnet of the ratchet assembly interacts with the magnetically attractable armature to generate a ratcheting feedback in response to rotation of the knob assembly when the friction disc assembly is in the first position.

A push button consists of component parts including a plunger, a retainer, a spring and an end cap. The plunger reciprocates within the retainer which has three main portions: an upper portion closely holds the button on the top of the plunger and includes a rectilinear recess that can receive a square midsection of the plunger. A middle portion of the retainer comprises an enlarged cavity that provides the side clearance for the plunger pin's enlarged square midsection to rotate. The cavity is bounded above and below by opposing roof and floor camming structures which engage the corners of the plunger midsection that causes it to rotate. A spring within the retainer biases the plunger upward. An end cap affixed to the bottom of the retainer captivates the plunger and spring assembly and provides attachment means to affix the push button assembly to a supporting structure.
