"The invention is concerned with a blinker Encoder in which the hot wire is made of a material that has a positive temperature coefficient * If necessary, a resistor with ne ~ is created parallel to the hot wire of the link transmitter divine temperature coefficient switched »or A resistor with a positive temperature coefficient was placed in series with the hot wire *

The previously known hot wire flasher in the simplest and cheapest version have the disadvantage that calibration impulses only take place after the bit wire has been heated up for a relatively long time can be submitted * ifaeh einohalten dee It takes about one second * to turn the turn signal light selection switch
