摘要： Electrical contact system with a first and a second contact (1, 5), each having a contact surface (4, 8). The first electric contact (1) has a mesostructured electric contact portion (14) with a plurality of slots (15) and ridges (16) formed between neighboring slots (16) of the plurality of slots (16). These slots (15) and ridges (16) extend in a direction running transversely to said switching plane (X-Z) form a plurality of current paths (16). The current paths (16) are inclined to the first contact surface (4) at a first angle (17) measuring less than 60 degrees such that an interruption current (12) flowing through the mesostructured electric contact portion (14) and through an electric arc (11) extending in between the first contact surface (4) after lifting the first contact surface (4) off the second contact surface (8) pushes said electric arc (11) in the direction of the apex of said first angle (17) from a first position (18) to a second position (19).

摘要： Processes for manufacturing touch sensors with one or more guard traces to reduce the effect of moisture damage are provided. One example process can include forming one or more guard traces between an edge of the touch sensor and the metal traces that route the drive and sense lines to bond pads. The one or more guard traces can be uncoupled from the drive lines and sense lines to protect the inner metal traces from moisture damage. In some examples, ends of the one or more guard traces can be coupled to ground by copper. In other examples, ends of the one or more guard traces can be coupled to ground by indium tin oxide or the one or more guard traces can be coupled to ground by a strip of indium tin oxide. In yet other examples, the guard trace can be floating (e.g., not coupled to ground).

摘要： A contact assembly for an electrical device and a method for making such an assembly are presented. The contact assembly comprises a substrate and a contact material disposed on the substrate. The contact material comprises a composite material comprising a refractory material and a matrix material. The matrix material has a higher ductility than the refractory material. The composite material further comprises a core region and an outer region bounding the core region, the core region having a higher concentration of the refractory material than the outer region. The method applies cold spraying a blended feedstock to produce a layer that includes the composite material described above.

摘要： Examples are disclosed that relate to magnetically aligned switching circuits. One disclosed example provides an electronic component comprising a first terminal, a second terminal, and a deformable host material arranged between the first terminal and the second terminal. Aligned magnetically within the host material is an ensemble of particles each comprising a ferromagnetic material, each particle having greater electrical conductivity than the host material. The ensemble of particles is configured to form at least one complete conduction path from the first terminal to the second terminal.

摘要： A contact pin for a high-voltage and/or medium-voltage switch includes a contact tip of arc-erosion resistant material, a tubular support sleeve connected to the contact tip and a support core in the sleeve. The contact tip is in a forward region of the contact pin where arcs arise during use. The sleeve is in a rearward region of the contact pin, adjoining the forward region, where no arcs arise during use. A pipe contact includes an arc-erosion resistant annular contact and a support pipe connected to the annular contact. The annular contact is in a forward region of the pipe contact where arcs arise during use, and the support pipe is in a rearward region of the pipe contact, adjoining the forward region, where no arcs arise during use. Methods for producing a contact pin and a pipe contact are also provided.

摘要： The invention relates to a method for producing at least one functional region on an electrical contact element such as, for example, a switching contact or a plug type contact. In order to prevent the high environmental burden which is disadvantageous in wet-chemical methods and to overcome the restriction to a very small number of materials caused in hot dip methods in physical technical terms, and to substantially improve the spatial possibility for selection and structuring which is insufficient in both techniques, there is provision according to the invention for at least one material coating to be applied mechanically in a highly selective manner to the contact element in the functional region and subsequently highly energetic thermal radiation such as, for example, a particle beam in the form of an ion and/or electron beam, to be directed onto the at least on material coating.

摘要： A method for control device adjustment comprising applying a preload simultaneously to a plurality of shafts of a control device so as to take up initial assembly play, wherein the control device comprises an upper actuating element that is movable relative to a lower supporting mounting, a lower supporting mounting, a switch that is actuated by the upper actuating element, and an articulated structure that is interposed vertically between the upper actuating element and the lower mounting to keep the upper actuating element parallel to a horizontal plane during its vertical downward movement relative to a frame, and the at least one shaft. The method also comprises providing an adjustment stop fixed relative to the lower mounting and forming a stop surface that interacts with a facing portion of the shaft.
