So that the parts and connections of a component, particularly a Giant Magneto-Resistor, may withstand external forces, a meander group (M,M) with at least one meander element (.n,.n) is positioned in both connection elements () between a component cell () and the straight functional connection element (A,A). A capacitor unit () is mounted on the meander group (M) of the first connection element () and on the meander group (M; of the second connection element ().

In order to configure the downshift method, and to create signals for an automobile automatic transmission more conveniently, a tilting device of a multi-function device with at least one moveable magnet element as a downshift sensor device is used. When a pedal element causes actuation of a magnet element, a downshift characteristic curve (KL ) is generated with a curve-shaped increase and a maximum followed by a curve decrease (KLS) that ends in a stop window ( ). A downshift point (KP) is determined using a tolerance window ( ) with a path width, which corresponds to a downshift signal (KS) on a characteristic motion curve (AS) of a motion sensor element.

Method and apparatus for producing downshift signals

To make it possible for a rotation angle sensor to be manufactured and assembled more easily and more accurately, the part components of a stator element ( ) made of a ferritic material are held in a sintered stator body, made by a sintering technique, by at least one holding element in a holding recess of a base element made of a non-magnetizable material. A magnetic holding device ( ) is a holding element made by a metal injection molding (MIM) technique with an at least partly formed magnetic isolation zone and at least one recess. An annular magnetic element ( ) is attached inside the MIM holding device by means of at least one slit-shaped recess and at least one compatible linking element, and positioned at a given angle &agr; in relation to a gap, between the sintered stator bodies.

So that a device for producing selector positions is easy to operate, the stop positions of which can be taken in securely and largely free of mechanical wear, and so that it is easily adaptable, in particular to the respective operating conditions, a position transmitter unit ( ) is provided which is movable along a longitudinal axis, and thereby its position transmitter teeth can be fixed with respect to the teeth of a first position detector element ( .n). The position transmitter unit ( ) can be shifted with a finger body along the longitudinal axis into a recess, and thereby a second rotation body can be placed on a second position selector unit, and this position can be detected by a second position detector element ( ). The position transmitter unit ( ) can be moved with a moving device ( .n) via a second position selector unit two dimensionally with respect to a base body ( ), and this position can be detected by third position detector elements ( ).
