A method and an apparatus for generating a horn actuation signal. A load cell is placed inside a steering wheel, which changes its resistance when being stressed or deformed by a force transmitting part of the steering wheel. An actual voltage (V.sub.a) depending on the resistance of the load cell is measured and the horn actuation signal is generated based on the measurement of the actual voltage (V.sub.a). The actual voltage (V.sub.a) depends additionally to the resistance of the load cell and on an adjustable voltage (V.sub.ad) generated by an adjustable voltage generation unit. Additionally, the result of the measurement of the actual voltage (V.sub.a) is permanently compared to a defined value, and the adjustable voltage (V.sub.ad) is adjusted in response to the difference between the result of the measurement of the actual voltage (V.sub.a) and the defined value at least as long as no horn actuation signal is generated, such that closed circuit for controlling the actual voltage (V.sub.a) is provided.

A touch key of an interface for an aircraft avionics system. The touch key includes a button, a mechanical switch, and a sensor. The mechanical switch is configured to be actuated when the button is pressed. Actuation of the mechanical switch sends a switch signal to the aircraft avionics system. The sensor is configured to detect when the button is being touched independent of whether the button is being pressed. The sensor sends a touch signal indicating that the button is being touched to the aircraft avionics system.

An output-switch control system for an AC-DC power supply includes a push-button switch that has two triggers. The triggers correspond to different contacts of a detecting circuit, respectively. When the push-button switch is pressed to make the triggers and the contacts turn into a close-circuit state form an open-circuit state, the detecting circuit outputs a power-source-on signal, and when the push-button switch is pressed again, and either of the triggers and the contact turn into the close-circuit state form the open-circuit state, the detecting circuit outputs a power-source-off signal immediately. With the dual-transition signal certification at the contacts, safe output-switch control can be achieved, so as to provide a user with operational safety.

The present disclosure provides a touch panel assembly and an electronic device. The touch panel assembly includes a touch panel, a touch switch, and a transmission assembly. The touch panel receives a touch operation from a user. The touch switch is positioned below the touch panel and located at a center position of the touch panel. The transmission assembly drives the touch panel to ascend and descend along a vertical direction synchronously and across an entire touch surface, and the touch panel activates the touch switch while descending. When subject to a given force, any touch areas of the touch panel can be pressed down, the touch panel stably moves synchronously and across its entire touch surface, so as to increase product stability. The touch panel assembly can achieve technical effects of a uniform touch feedback and the touch panel's stable movement, and so as to effectively improve user experiences.

A multifunctional selection operation switch apparatus includes: an operation member including multiple operated portions and capable of being rotationally operated, the operated portions being capable of selective contact operation; a rotational displacement detecting device capable of detecting rotational displacement of the operation member; an operation target detecting device capable of detecting on which of the operated portions contact operation is performed; and a controlling device outputting a command signal corresponding to the displacement and the one operated portion, based on detection results of the detecting devices. Accordingly, even if the operation member is a single member, multifunctional selection operation can be performed without difficulty by outputting, whenever necessary, a desired command from multiple operation commands. It is not necessary to mechanically and operatively connect the operation member and the operated portions by a structurally-complicated interlocking mechanism, thereby achieving reduction in the number of parts and cost.
