A control system includes a control device and a display device. The control device includes plural keys in a specified arrangement. The plural keys are marked with plural first-layer options. Each first-layer option extends plural second-layer options. The display device is in communication with the control device. A display image of the display device includes plural display blocks. An arrangement of the plural display blocks is identical to the arrangement of the plural keys. When one of the plural keys is triggered by a user, the second-layer options extended from the first-layer option corresponding to the triggered key are shown on the display image, and the second-layer options are included in the corresponding display blocks, respectively. A specified option of the second-layer options is selected by the user when the key on the control device and at a position corresponding to the specified option is triggered.

A key switch is provided, which includes a base, a cap, a first linkage rod, a second linkage rod, an elastic contraction element, at least one activate member and a thin film circuit unit. The base includes a plurality of first connection portions and a plurality of second connection portions. The first linkage rod is movably connected to the first connection portions and the cap. The second linkage rod is movably connected to the second connection portions and the cap. One end of the elastic contraction element is connected to the first linkage rod, and the other end thereof is connected to the second linkage rod. The activate member is disposed on one of the first linkage rod, the second linkage rod and the cap. The thin film circuit unit includes an activate portion.

A keyswitch structure includes a base, a cap disposed corresponding to the base, a restoring member disposed between the base and the cap, and a tactile adjustment unit. The cap has a cam portion movable relative to the base. The restoring member is configured to provide a restoring force to enable the cam portion to move away from the base. The tactile adjustment unit is disposed corresponding to the cam portion and includes a holder and a tactile feedback member mounted on the holder. The holder is movable relative to the base to change a position of the tactile feedback member relative to the cam portion, so as to change a pressing force required for the cam portion to move toward the base.

Various implementations include a switch assembly that includes a housing and at least two printed circuit boards (PCBs) that are disposed within the housing and are axially arranged relative to each other. One or more force sensors are disposed on one of the PCBs, and, in some implementations, the one or more force sensors receive force input received by a touch overlay plate. Signals from the force sensors are processed to determine a magnitude, acceleration, and/or location of the force input, and a haptic feedback response is received by the touch overlay plate. The haptic feedback response is based on the force magnitude, acceleration, and/or location of input, according to some implementations. Axially arranging the PCBs reduces the footprint of the switch assembly and allows for the inclusion of more electrical components in the switch assembly, according to some implementations.

The invention relates to an operating unit for a vehicle, provided with an operating element (12) having an operating interface (14) with multiple symbol fields (16), to which are assigned operating functions that can be triggered with the actuation of the operating element (12). The operating element (12) is arranged on a support structure (18) such that it can be pressed down in a resettable manner and by means of an actuation object, in particular by means of the finger of a hand. The operating unit (10) is also provided with a mechanical switch (22) which can be actuated when pressing down the operating element (12), a controllable press-down force threshold switching device (34) for switching the force to be overcome to press down the operating element (12) between a first threshold value and a second threshold value that is smaller in comparison to the first threshold value, an actuation sensor system (30) for detecting whether, when the operating element (12) is actuated, the actuation object contacts same within one of the symbol fields (16) of the operating interface (14), and an evaluation and control unit (32) which receives signals from the actuation sensor system (30) or, inter alia, from the actuation sensor system (30), and which only causes the press-down force threshold switching device (34) or, inter alia, the press-down force threshold switching device (34) to switch from the first threshold value to the second threshold value by changing its control, when the actuation object within one of the symbol fields is in contact with the operating interface (14) within one of the symbol fields (16) with an actuation of the operating element (12). An electromagnet or permanent holding electromagnet (40) is used as the press-down force threshold switching device (34).

An electronic device includes an enclosure and a keyboard positioned within the enclosure. The keyboard includes a substrate and a key mechanism. The key mechanism includes a keycap support mechanism, a keycap supported by the keycap support mechanism and movable relative to the substrate, a ferromagnetic component attached to the keycap support mechanism, and a selectively magnetizable magnet. The selectively magnetizable magnet system may include a magnetizable material and a coil configured to selectively magnetize and demagnetize the magnetizable material. The key mechanism may include a collapsible dome biasing the keycap toward the extended position.
