A hydraulic switching device (1; 101) for use in a circuit (7; 107) that comprises at least two movable drive units (2; 3) with a first direction of movement in the functional direction or a counter-direction, where said drive units can be pressurized with a pressure medium via at least two connection lines (13, 26; 24; 31), whereby externally controllable selector switches (14; 15; 16) are provided for controlling the pressurization with a pressure medium, is designed so that exactly one controllable selector switch (14; 15; 16) is provided for each drive unit (2; 3; 6) and at least two drive units (2; 3) are interconnected via logical AND and/or OR valve elements (22, 25; 141, 142, 143, 144) so that at least with a resulting introduction of force to the first drive unit (2) in the functional direction (F), a force release of the second drive unit (3), and with an introduction of force to the first drive unit (2) in the counter-direction (G), an introduction of force to the second drive unit (3) in the functional direction (F), in the counter-direction (G) or a force release is made possible (FIG. 1).
