[origin: DE4445081C1] The three setting switch drive has a switch axis which can be rotated into the switch settings ON, OFF and EARTH. The switch axis can be operated manually from OFF to ON and from OFF to EARTH and reverse. The three setting switch drive is realised by a step switch gear whose rotatable switch axis is formed by an operating shaft isolator (BWT) and operating shaft earther (BWE). The three setting switch drive has separate operating shafts for isolator and earther, a common drive shaft, internal switch setting locking and mechanical and electrical switch setting display.
