An electrohydraulic switching device is proposed for emitting electrical control signals as a function of supplied pressure signals, having a housing which has two longitudinal holes and in which a piston is arranged such that it can be displaced axially, which piston can be acted on by the input pressure and is prestressed by means of a compression spring against the input pressure, and having an operating element, which is operatively connected to the piston, for operating electrical switching devices. In order to avoid bouncing of the switch as well as sticking and welding of the relay contacts, the electrical switching devices are formed by two separate switches S1, S2 which interact with a relay SR which has a self-latching behaviour and is integrated in the housing 1. <IMAGE>
