Abstract: The invention creates a micromechanical component, in particular a pressure sensor, comprising: a substrate (2) that has a membrane region (10) and a surrounding region of the membrane region (10); at least one measuring resistance (4a, 4b; 41, 42) provided in the membrane region (10) and modifiable by deformation of the membrane region (10); a corresponding evaluation circuit (50) provided in the surrounding region, an interference effect on the measuring resistance (4a, 4b; 41, 42) being producible by way of a deformation of parts, in particular conductor paths, of the evaluation circuit (50) relative to the substrate (2); and at least one patch (60; 70, 70′) provided in the surrounding region and/or in the membrane region (10) and made of a material such that by way of a deformation of the patch or patches (60) relative to the substrate (2), an analog interference effect can be generated in such a way that the interference effect acting on the measuring resistance (4a, 4b; 41, 42) can be compensated

Abstract: A micromechanical structure and a corresponding manufacturing method are described. The structure includes a substrate (10), which has an anchoring device (20), and a centrifugal mass (30), which is connected to the anchoring device (20) via a flexible spring device (40), so that the centrifugal mass (30) is elastically deflectable from its rest position. The centrifugal mass (30) has clearances and is designed to be deflectable by etching a sacrificial layer (50) underneath it. The sacrificial layer (50) is present in a first area located underneath the centrifugal mass (30) with a first etchable thickness (d1), and in a second area located underneath the centrifugal mass (30) with a second etchable thickness (d1+d2+d3), the second thickness being greater than the first thickness (d1). The centrifugal mass (30) is structured in the first area so that in etching only a maximum of two etching fronts may come together in order to limit the etching residue deposits.

Abstract: A pressure switch is described with a pressure connection (11), with an electrical pressure sensor (19) to generate a pressure-dependent electrical signal, with an operator-device and/or an adjusting device (16-18) to input at least one pressure switch threshold and with at least one electrical switch output (16-18) [sic; 13,14]. The pressure switch can be adjusted by operation of the operator device (16-18) in such a manner that the electrical signal corresponding to the instantaneously applied pressure (p) is saved as the first saved pressure value (S1) and the electrical signal corresponding to a pressure (p) applied temporally thereafter, is saved as a second saved pressure value (S2), where these two saved pressure values (S1, S2) define the pressure switching threshold(s) in the operating mode. Thus, the saved pressure values can be specified very easily and in a variable manner and saved, and a great variability of operating modes is possible.

Abstract: A connecting device for the electrical connection of a support board to another component is proposed. The support board has a recess open toward its end and delimited to the side by spring arms, contact faces for the electrical connection being arranged thereon.

Abstract: A plug connector having a main body, which has at least one connecting unit including an opening delimited at the side of an elongated transversely elastic gripping rib. The opening constitutes a plug socket, into which a plug element may be inserted and acted upon by the gripping rib. The gripping rib has a concave shaped longitudinal edge portion facing away from the plug socket such that the width of the gripper rib increases toward the two ends of the rib.

Abstract: A pressure sensor includes a metallic membrane and a frame. For detecting the deflection of the membrane, a silicon bridge element having piezoresistive resistor elements is arranged on the membrane and the frame.
