The isolating switch (1) contains an isolating switch housing (2) and at least two switching points (18, 19, 20) which are arranged in the isolating switch housing (2), are of axially symmetrical design, and each have one fixed switching element (7, 8, 9) and one switching element (15, 16, 17) which can move along the switching point axis (21, 22, 23). A drive shaft (11) leads into the isolating switch housing (2). From this drive shaft (11), power is transmitted via a gearbox (25) to the movable switching element (15, 16, 17). The gearbox (25) has for each switching point (18, 19, 20) a control cam (26, 27, 28) which is fixedly connected to the movable switching element (15, 16, 17), is aligned transversely with respect to the shaft axis (11) and is displaceable. It also contains a lever (29, . . . 34; 47) which is attached to the drive shaft (11) and interacts with the control cam (26, 27, 28). This lever is frictionally coupled to the control cam (26, 27, 28) in such a way that in each angular position of the drive shaft (11) the control cam (26, 27, 28), and the movable switching element (15, 16, 17) which is attached thereto are positioned in a defined fashion in the direction of the switching point axis (21, 22, 23). The isolation switch compact design permits precise control of the switching points.
