Product Description

As a convenience feature of the windshield wiper intermittent and wipe/wash operation are implemented in most of the automobiles. The U641B is the low-cost solution for an accurate timing function control. Wipe/wash mode has priority over interval mode. Interval pause and after wiping time can be set to fixed values by using resistors in a broad time range. Added value can be provided with an individual, continuous adjustment of the interval pause by a potentiometer which may be built into the stalk. For proper operation it is mandatory to feed the signal of the wiper motor's park switch into U641B.
