A spring plate includes a central portion; an opening that is positioned at a center of the central portion; and a strip extending from a part of an inner edge of the opening that is positioned at the center of the central portion. The strip includes a first width that is positioned adjacent to the part of the inner edge of the opening and a second width that is positioned adjacent to an end of the strip. The first width of the strip is wider than the second width that is positioned adjacent to the end of the strip.

A switching control arrangement, in particular for a motor vehicle, having a movable actuating surface that interacts with a displacement element in such a way that the actuating surface can be moved substantially linearly, over at least one distance, out of an initial position and into an actuating position. The displacement element has at least one elastic element arranged so as to be clamped in place. The actuating position can be designed as a switching position, such that the actuating surface, when in the switching position, has a switching effect on a switching element, a sensor, or the like. The elastic element is designed as a planar element with a small thickness in the form of a membrane, such that it is possible for the elastic element to be elastically deflected substantially perpendicularly to the surface of the membrane.

A push switch includes a movable contact including a dome part that is shaped like a dome and configured to be inverted in shape when pressed, and a fixed contact including a first fixed contact, the movable contact being configured to be brought into contact with and away from the first fixed contact. The push switch is configured such that an operating load necessary to press the movable contact gradually increases after the movable contact starts to be pressed, decreases thereafter when the dome part is inverted, and increases again when the movable contact is further pressed, and the dome part contacts the first fixed contact after an inflection point at which the decreased operating load starts to increase again.

A low travel switch assembly and systems and methods for using the same are disclosed. The low travel dome may include a domed surface having upper and lower portions, and a set of tuning members integrated within the domed surface between the upper and lower portions. The tuning members may be operative to control a force-displacement curve characteristic of the low travel dome.

A sensor includes a base layer and a pressing unit protruding with respect to the base layer. The pressing unit includes a first structure unit and a hollow second structure unit disposed on the first structure unit and having a bottom side opened. The second structure unit has a shape portion on a surface facing the base layer.

In a first aspect of the present disclosure, a push switch includes a substrate including a first electrode and a second electrode arranged on an upper surface of the substrate, the second electrode arranged around the first electrode; and a resilient member that is arranged on the second electrode over the first electrode. The substrate includes a recess in a lower surface of the substrate, and the recess is positioned below the first electrode that is arranged on the upper surface of the substrate.
