A switch assembly has two contacts; a switch having an open position in which the contacts are electrically separated from one another; and a switch status detector positioned remotely from the switch.

A steering switch device, which is mounted on a steering wheel, includes a linear switch that includes a hollow insulator having restorability and two electrode wires arranged spirally along an inner surface of a hollow part in the hollow insulator while being kept not in contact with each other, wherein a winding pitch coiling spirally the electrode wires is at least not more than 10 mm, and a detecting device that detects a press of the linear switch by sensing a contact of the electrode wires. The linear switch is arranged so as to be along at least part of a surface of the steering wheel.

A contact device includes: a contact block which includes a fixed terminal including a fixed contact formed thereon, and a movable contactor including a movable contact formed thereon; and a driving block including a driving shaft to which the movable contactor is attached, the driving block configured to drive the movable contactor. The contact block includes: a biasing portion configured to bias the movable contactor toward one side in a driving shaft direction; and a yoke disposed at least on an opposite side of the movable contactor in the driving shaft direction while the movable contact is in contact with the fixed contact. The biasing portion includes a biasing end configured to make biasing force act on the movable contactor by pressing a member other than the yoke.

The present application provides a force feedback device, including a base; a button assembly, comprising a button body, a button formed by protruding and extending the button body away from the base, a first rotary shaft connected to one side of the button body close to the base and rotatably connected to the base, and a swing rod formed by extending on one side of the button body close to the base and rotatably connected to the first rotary shaft; a driving assembly including a driving unit fixed to one side of the base and an output shaft connected to the driving unit; a gear assembly rotatably arranged on the base. One end of the gear assembly is connected to the output shaft, and the other end thereof is connected to the swing rod.

One variation of a keyboard system includes: a substrate including an array of inductors; a tactile layer arranged over the substrate defining an array of key locations over the array of inductors; an array of magnetic elements, each arranged within the tactile layer at a key location configured to inductively couple to an adjacent inductor and configured to move relative to the adjacent inductor responsive to application of a force on the tactile layer at the key location; and a controller configured to read electrical values from the inductors. In response to detecting a change in electrical value at a first inductor, the controller also configured to: register a first keystroke of a first key type associated with a first key location defined over the first inductor; and drive an oscillating voltage across the first inductor to oscillate the tactile layer over the substrate during a haptic feedback cycle.

Automatic transfer switches and methods of forming such switches are disclosed herein. One automatic transfer switch disclosed herein includes a first source bar structured to connect to a first power source, a second source bar structured to connect to a second power source, and a stationary bar structured to be coupled to a load. The automatic transfer switch also includes a first movable bar and a second movable bar each electrically coupled and rotatably connected to the stationary bar. The length of each movable bar and the angle of each movable bar with respect to the stationary bus bar are selected to approximately balance the contact force on each movable bar. Thus, smooth and reliable operations of the automatic transfer switch can be achieved.
