ABSTRACT:
A pressure supply system for the generation of the auxiliary pressure of a hydraulic brake system for motor vehicles comprises an accumulator, a hydraulic pump driven by electromotive force and a pressure switch (1) controlling the turning on and off of the hydraulic pump. The pressure switch (1) includes a switch piston (2) having a piston rod (5) mechanically actuating in a pressure-responsive manner, successively, two or three switches (8,9,10). The pump motor (26), by way of these switches, and by way of a relay, is turned on when a bottom pressure limit value (P.sub.U) is reached, and turned off when the upper pressure limit value (P.sub.O) is reached and exceeded. A holding circuit is connected in the electric circuit, in which are provided the switches (8,9,10) of the pressure switch (1), which holding circuit ensures an abrupt switch-over of the relay into the other switching position when a slow approach of a pressure (p) to the pressure limit values (p.sub.U, P.sub.O) causes fluttering of the relay contacts.
