An electrohydraulic switching device is proposed for emitting electrical control signals as a function of the supply pressure signal, having a housing which is closed by means of a closure cap, having an axially displaceable piston on which the input pressure can act and which is prestressed against the input pressure by means of a compression spring which is supported on a spring plate which is located on the piston, the prestressing of said compression spring being adjustable by varying the relative position of the piston with respect to the housing, and having an operating element which is connected to the piston in a positively-locking manner, for operating electrical switching devices. In order to specify a switching device which is structurally simple, can be produced cost-effectively, can be adjusted simply and operates reliably, the piston is constructed in two parts and the closure cap is at the same time used as a holder for the switching devices. <IMAGE>
