Abstract

A circuit arrangement, in particular for a wiper arrangement for motor vehicle windshields, having an electric wiper motor and a step-switching unit for the wiper motor that can be actuated via a control device, and wherein at least one output of the control device that is assigned to a specific wiper speed is connected to at least one input of the step-switching unit that determines this wiper speed. A switching means (18) is parallel-connected to the outputs (20, 24) of the control device (12), by way of which a voltage source (U.sub.bat) can be connected with the inputs (22, 26) of the step-switching unit (14), which are assigned to the outputs (20, 24) of the control device (12).
