Abstract: An electrical device has a printed-circuit board secured to a cover of the electrical-device housing, as well as a heat-dissipation mat arranged on a housing wall. The cover secured to the housing, as well as guideways of the housing, in which guideways the printed-circuit board is received, exert a tension force on the printed-circuit board, because of which electronic components arranged on the printed-circuit board, under conditions of intimate contact with the heat-dissipation mat, are embedded into the heat-dissipation mat. This is achieved by introducing the printed-circuit board in inclined position into the housing and, shortly before it reaches its final position, swivelling the printed-circuit board toward the wall of the housing having the heat-dissipation mat.

Abstract: A valve block unit comprising a valve block and a valve block lid is proposed, which to facilitate installation and to protect electrical contact pins against bending or damage is equipped with an intermediate plate that has guide openings. In a dismounted state of the valve block and valve block lid, this intermediate plate protectively receives the contact pins. The intermediate plate is subject to the force of compression springs, which are compressed when the valve block and the valve block lid are brought together for installation. The contact pins then protrude from the protective intermediate plate and enter the contact bushes intended for them. This assures safe electrical connections, designed for ease of manufacture, within the valve block unit. The valve block unit is intended for use in motor vehicle brake pressure modulation systems.

Abstract: An arrangement for dissipating heat from power components assembled on a printed-circuit board dissipates heat generated in the power components to the side of the printed-circuit board that is removed from the components. The printed-circuit board may have heat-transfer bore holes, and a heat-conducting material applied in the area of the power components, the heat-transfer bore holes, and the side of the printed-circuit board facing away from the power components. The side of the printed-circuit board that is removed from the power components may be coated with an insulating enamel and with a flexible heat-conducting enamel.

Abstract: An electrical switching device has a housing composed of an electrically conductive material, at least one conductor plate having a region of an electrically conductive material and arranged in the housing, plug connection means extending from the housing in a sealed manner, and an element for electrically conductive connection of the conductor plate with the housing. The element for electrically conductive connection includes a mechanically prestressed spring element. The spring element has one end abutting against the conductor plate in the region of an electrically conductive material and another end fixedly connected with the housing.
