More to the point these days it is done in software I think, so there are no interesting details.

An intermittent wiper circuit turns on the wiper (in parallel) with the wiper switch and then turns off before the end of the cycle. There are lots of circuits to do this using everything from 555 timer, microcontrollers to simple RC timing circuits, generally all have some variable timing. They use things such as relays or SCRs as the switch.
