Abstract: 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).

Abstract: A switching apparatus includes a grounded, insulating gas-filled housing, the housing having a housing wall, and a power circuit-breaker disposed in the housing. The apparatus further includes a current connection for a first busbar, a current connection for a second busbar, and a current connection for a load outgoer. The apparatus further includes a grounding switch disposed in the housing, the grounding switch being connected between the power circuit-breaker and the current connection for the load outgoer, and a busbar disconnector, the busbar disconnector being connected between the current connection of the first busbar and the power circuit-breaker and between the current connection of the second busbar and the power circuit-breaker. An outwardly extended, first tubular flange arrangement is attached over a first opening in the housing wall, and an outwardly extended, second tubular flange arrangement is attached over a second opening in the housing wall.
