Zusammenfassung: | The utility model provides a windshield wiper intermittent controller comprising a windshield wiper motor and a wash motor. The windshield wiper intermittent controller is characterized in that a windshield wiper has arranged therein a starting position accurate timing circuit including a third resistor, a fourth resistor, a first capacitor, an eighth resistor and a fourth darlington block, and an accurate delay discharging circuit including a ninth resistor, a third darlington block, a second diode and a second capacitor. The windshield wiper intermittent controller solves the problems that conventional windshield wipers are small in working current, poor in reliability, inaccurate in delay, and short in service lifetime and the problems that conventional windshield wipers are susceptible to external influence and have negative impact on the service lifetime of windshield wipers motors due to the short service lifetime themselves. The windshield wiper intermittent controller is reasonable, simple and compact |
