ABSTRACT:
An apparatus for intermittently controlling windshield wipers, comprising a setting switch which is capable of being manually activated, a microconller responsive to the activation of the setting switch, means for programming a time interval into the microcontroller in response to activation of said setting switch, whereby the microcontroller initiates a sweeping action of the windshield wipers corresponding to the time interval between activations of the setting switch and continues to initiate a sweeping action of the windshield wipers during the programmed time interval until a subsequent activation of the setting switch, and, either means for decreasing the time interval after setting of the programmed time interval by a single subsequent activation of the setting switch or means for increasing the time interval after setting of the programmed time interval by two subsequent activations of the setting switch. A method for intermittently controlling windshield wipers is also disclosed.
