Abstract: A forming tool for shaping a workpiece, in particular a flat metal sheet, includes a female die, a blank holder, and a male die, all of which are movable relative to one another. The female die, the blank holder and/or the male die may be temperature-controlled in at least some portions thereof.

Abstract: A wedge driving tool for cutting and/or non-cutting shaping of a sheet metal workpiece in a press includes a mould- and/or tool-bearing working slider, which may be displaced between a slider bed and a driver at a predetermined angle. For obtaining a working slider which may be continuously angularly adjusted, segmental disks are in each case arranged on both sides of the working slider in a continuously movable manner with respect to an angle of rotation, in each case, on the slider bed and the driver or on the working slider and the driver. The segmental disks, in each case, being arranged in pairs on an axis of rotation, are non-rotatably mutually connected along their chord-type boundaries such that corresponding straight-line guides, particularly for the working slider, are arranged in these connections.

Abstract: In an electrical switch being subject to high contact pressure and using contacts of relatively soft contact material, the isolating or electrical resistance is impaired by contact wear. A contact and a counter contact spring supported by an isolating support before and/or behind the contact with an area the surface of which is located lower than the level of the topside of the contact. On at least one side of said recess area, the isolating support is provided with an elevated portion which also extends in the direction of relative movement of the contact spring and on which the contact spring rests when the switch is in its open position.
