The present invention relates to a Hall Principle-based LED lit mechanical keyboard switch comprising a keymodule, permanent magnet, housing, LED lamp, Hall switch, elastic strip, top cover and spring; the keymodule consists of a plunger and a slider, the plunger has a key on top and a first locating pole at bottom; the slider has magnet mounting slot on its side wall; a second locating pole is provided at the bottom center inside the housing, the second locating pole is provided with a guide hole at its center, and a LED lamp mounting hole is provided on one side in the housing; Hall switch mounting hole and plunger slideway are provided on the neighboring side next to the side of the housing on which LED lamp mounting hole is provided.

A control element comprising a support; a control part which defines at least one operating surface, which is movable or elastically yielding if an operating force F acts upon the operating surface; a layer structure that is disposed between the control part and the support and that is elastically deformed if an operating force F acts on the operating surface. The layer structure has at least one first electrode associated with the support and a second electrode, which is associated with the control part and disposed underneath the operating surface, for the definition of a measuring capacity varying in accordance with the operating force. The layer structure further has an intermediate layer having a recess which is disposed between the first and second electrodes for defining a hollow chamber; and means for venting the hollow chamber. The means for venting is integrated at least partially into the intermediate layer.

An overhead ceiling device for vehicles, such as airplanes. The device includes a faceplate, keypad, PCB, body, light module, and an outer mounting compression ring body. The faceplate includes lens for lights and holes for buttons. Keypad includes buttons that can protrude from the holes in the faceplate. The keypad is seated over the PCB, wherein the PCB includes indicator lights and key input modules for the buttons. The PCB is seated over the flanged plate of the body. The faceplate, keypad, PCB and the body have a central hole for receiving the light module. The light module includes a reading light.

An interior member includes a first skin material, a second skin material, and transducers. The first skin material includes a first exposed part exposed to a cabin interior, and a first embedded part embedded on a cabin exterior side from the first exposed part. The second skin material includes a second exposed part exposed to the cabin interior and adjacent to the first exposed part, and a second embedded part embedded on the cabin exterior side from the second exposed part and joined to the first embedded part. The transducers each include a main body arranged directly back of the first exposed part, and a wiring part disposed directly back of at least the first embedded part and electrically connected to the main body. An end of each wiring part is disposed on the cabin exterior side of the first embedded part.

The present invention relates to a magnetic push-button (10) comprises a fixed body and a body which is movable with respect to the fixed body along an axis of movement (X); one of the bodies, called first body (21), comprising: a magnetic element extending along the axis of movement (X) and defining a magnetic alternation along the axis of movement; the other body, called second body (22), comprising: a notching tooth made of ferromagnetic or magnetic material arranged opposite the magnetic element so as to create a push force by magnetic cooperation with the magnetic element, during a movement of the movable body (21) along the axis of movement (X); a magnetic detector placed opposite the magnetic element and configured for generating measurements quantifying each movement of the movable body along the axis of movement (X).
