Abstract

PURPOSE: To discriminate the quality of a glow switch easily and surely, by generating a high voltage pulse through the lighting of the glow switch and measuring the pulse width and voltage level of the high voltage pulse.
CONSTITUTION: Both contacts 6b, 6c of a glow switch 6 is connected to the input terminal of a kick voltage measuring circuit 7. The kick voltage measuring circuit 7 inputs a kick voltage from both ends of the glow switch, the pulse width and voltage level of the kick voltage are measured, and the number of times when the pulse width and voltage level at the production period of a start signal exceed a preset value, is counted, and the count data is transferred to a microcomputer 9. Further, the kick voltage measuring circuit 7 feeds a failure high voltage pulse generating signal to the microcomputer 9 when the pulse width and voltage level of the kick voltage exceed preset conditions. The microcomputer 9 judges the propriety of the glow switch 6.
