An output module for a PLC includes an output circuit. This output circuit is open or closed selectively between a power supply terminal (to which a power supply voltage is supplied) and an output terminal (connected to a solenoid). The output module includes a control apparatus which controls the operation of the output circuit. The output circuit includes switches connected in series to each other between the power supply terminal and the output terminal, and a current output section which performs an operation of short-circuiting terminals of the switch to pass a predetermined current through a path formed due to the short-circuiting. The control apparatus includes on/off control sections which controls on/off states of the respective switches, and diagnosis sections which perform a diagnosis on presence of a short-circuit fault in the respective switches based on diagnostic signals output from a low-potential terminal of the switches.

To provide an input operation device capable of detecting, using a simple configuration, a first operation of touching an operation surface with an operation body and a second operation of pressing the operation surface with the operation body. An input operation device 11 includes a detection value changing part 31, which changes a detection value of a capacitive sensor 12, and a supporting part 41, which supports a touch sensor part 21 in a state in which the detection value changing part 31 and the touch sensor part 21 are separated from each other. The detection value changing part 31 is arranged on a back surface 24 side opposite to the operation surface 22 of the touch sensor part 21, and changes the detection value depending on contact with the detection part 23. The supporting part 41 includes an elastically shape-changeable part 42, which elastically changes shape so as to bring the detection part 23 into contact with the detection value changing part 31 in response to pressing of the operation surface 22. The capacitive sensor 12 of the input operation device 11 generates a first detection value indicating a first operation of touching the operation surface 22 and a second detection value indicating a second operation of pressing the operation surface 22 toward the detection value changing part 31.

Systems, methods, and apparatuses are provided for a single or multi-dimmer system having improved reliable connectivity between a dimmer assembly and a switch or between two or more dimmer assemblies.

A button device includes a fixed support structure; a movable structure, laterally surrounded by the support structure and configured to deform at least in part under the action of an external force; and a fluid-tight protection cap. The movable structure includes a piston element, deformable elements having piezoelectric transducers arranged thereon, and anchor elements that couple the piston element to the deformable elements. When an external force acts on the piston element, the anchor elements transfer this force to the deformable elements and to the piezoelectric transducers, so as to sense the extent of this force.

An operator for controlling electrically adjustable furniture includes a housing and an actuation panel movably supported in the housing to form a cover body. A circuit board is provided in the housing, and a main control unit for detecting an actuation signal is provided on the circuit board. A first switch for generating a first actuation signal and a second switch for generating a second actuation signal are provided between the actuation panel and the main control unit, and a third switch for generating a third actuation signal is provided between a bottom wall of the housing and the main control unit. The main control unit issues a first command when simultaneously detecting the first actuation signal and the second actuation signal, and the main control unit issues a second command when simultaneously detecting the first actuation signal, the second actuation signal, and the third actuation signal.

An operating device for a motor vehicle, having a touch-sensitive operating element with a frame element and a central region. The touch-sensitive operating interface has a predetermined operating region at each of at least two predetermined touch positions for activating an operating function assigned to the respective operating region. The operating element is arranged to be displaceable at least partially along a translation axis that intersects the operating interface. The operating device has only one detection element, which is arranged facing an inner side of the touch-sensitive operating element that faces away from the touch-sensitive operating interface, and which is arranged to detect a displacement of each operating region along the translation axis.
