Abstract
The invention relates to a glow plug control device comprising a power transistor for switching the heating current on and off, a control unit for controlling the power transistor, a measuring resistor connected in series with the power transistor for measuring the intensity of a heating current, and a circuit board, which carries the power transistor, the control unit and the measuring resistor. The measuring resistor is connected to the circuit board via pins which are pressed into circuit board holes and which are made of an alloy that has a copper content of at least 80% by weight and a nickel content from 4 to 12% by weight. This disclosure also relates to the use of an alloy having a copper content of at least 80% by weight and a nickel content from 4 to 12% by weight for a pin of a press-in connection in a glow plug control device.
