Summary:A coaxial drive shaft system (5) is provided for a withdrawable unit (1) for insertion into a withdrawable unit compartment of a switchgear cabinet (100), wherein the drive shaft system (5) has an outer drive shaft (51) for moving a control contact system (13) and an inner drive shaft (52) for moving a main contact system (14) of the withdrawable unit (1). The drive shaft system (5) has an access opening (32) for inserting a first or second operating tool (91, 92) for driving the following drive shafts (51, 52) into their respective first or second rotational end positions. According to the invention, the inner drive shaft (52) is arranged such that it can be displaced axially against the force of a compression spring (17) in relation to the outer drive shaft (51). The inner drive shaft (52) can be rotated from one rotary end position to the respectively other rotary end position by means of the first operating tool (91) only in a pressed position.
