Apparatuses, systems, and methods of manufacturing are described that provide a rotary switch. An example rotary switch includes a substrate and a plurality of electrical contacts supported by the substrate. The rotary switch includes a resistor network of a plurality of resistors in electrical communication with the plurality of electrical contacts and a commutator that moves relative to the substrate along the plurality of electrical contacts. The commutator electrically connects a pair of adjacent electrical contacts so as to modify an output voltage of the rotary switch corresponding to a position of the rotary switch. Each resistor of the resistor network is positioned so as to electrically connect a respective pair of adjacent electrical contacts. Each resistor in the resistor network comprises a resistance value that is different from resistance values of other resistors in the resistor network.

Disclosed herein a user interface device includes a hinge configured to slide in a first direction along a rail extending in the first direction; and a knob coupled to the hinge to slide in the first direction and configured to detect a rotation input; wherein the knob includes a knob base coupled to the hinge, a bearing including a first member coupled to the knob base and a second member rotatable about a rotation axis with respect to the first member, and a knob body coupled to the second member and configured to rotate with respect to the knob base, wherein the knob body is detachably coupled to the second member.

A mechanical knob which may be designed and tuned according to various design conditions (size and the like of the knob) without restriction conditions such as a size, height, and the like, its push and rotation operations may be performed, and many parts are unnecessary unlike the conventional mechanical knobs. The mechanical knob apparatus includes a dial configured to transmit a force at which a user rotates or presses the knob to perform the rotation or push rotation of the knob as an exterior part of the knob exposed to the outside, a push operation unit coupled to the dial through a radial bearing to perform the push operation, and a rotation operation unit coupled to the dial to perform both the push operation and the rotation operation.

A system and method for operating a rotatable knob module with adjustable tactile feedback. The rotatable knob module includes a knob configured to continuously rotate about a center axis and an electronic processor. The electronic processor is configured to determine a current trailer angle, define a virtual center position of the knob based on the current trailer angle, and adjust a rotational torque of the knob when the knob is rotated from a first rotational position to a second rotational position based on a relative virtual rotational distance of the second rotational position from the virtual center position.

A push switch and a motor vehicle in which such a push switch is used. The push switch has a push cap, a baseplate, a switch element which is actuatable by the push cap, a first lever, and a second lever. The first lever and the second lever are mounted rotatably on the baseplate by means of bearing blocks and are each connected movably to the push cap at a first lever end. At a second lever end, the first lever and the second lever are connected movably to one another. The first lever and the second lever are designed such that they form mass compensation for the push cap.

Provided is an electronic module including a housing case for housing a relay, a heat transfer sheet placed on one wall portion of the housing case, a bus bar that is connected to the relay and is partially in contact with the heat transfer sheet, and a pressing portion that presses the bus bar against the heat transfer sheet.

A switch device includes, a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion, a first fixed terminal that contacts the movable terminal when the spring is not bent, a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring, a case including an opening, and a cover that closes the opening and is separate from the first fixed terminal. When the opening is closed by the cover, the first fixed terminal is positioned in the case by the cover.

A switch device includes a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion, a first fixed terminal that contacts the movable terminal when the spring is not bent, a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring, and a housing that accommodates at least the first fixed terminal. The first fixed terminal includes a first fixed terminal body that contacts the movable terminal, and a first fixed terminal connection pin bent sideward from the first fixed terminal body and mounted on a board. The housing includes a groove portion that allows for passage of the first fixed terminal connection pin.

A switch device includes a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion, a first fixed terminal that contacts the movable terminal when the spring is not bent, and a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring. The second fixed terminal includes a portion machined into a fixed contact that contacts the movable terminal.

A device having push button switches for operating a power seat of a vehicle, includes a switch module in which a plurality of push button type switches for an input operation to drive a power seat to a target position and in a target direction are modularized; a plurality of touch sensors embedded in the plurality of push button type switches and configured to indicate operating directions of the power seat; a main controller configured to determine an operating direction of the power seat according to a sensing signal from a touch sensor in which a touch sensing operation is performed among the plurality of touch sensors; and a display configured to display the operating direction of the power seat determined by the main controller as one arrow and visually guide a user.
