摘要：In the known command switch having a key rose (1), next to a switching insert(3), which can be rotated to actuate it from an \"off\" position to an \"on\" position and whichcan be pulled off in the \"off\" position, is a further switching insert which is closed oropened when a key is introduced, with the result that the introduced position of the key

can be indicated. The key has to be withdrawn here, to ensure that the switching action ofthe switching insert and therefore the indication are initiated. In this embodiment, theactuation of the further switching insert takes place via an extension plunger located onthe bottom of the cylinder in the key rose (1), that is to say the switching insert isactuated only in the fully introduced position. The command switch is to be improved tothe effect that an actuation of the additional switching insert (2) is associated with the key(6) introduced in any position, that is to say self-retained. This is achieved in that the keyrose (1) has, in the region of the introduction orifice (4) for the key (6), an actuatingelement (5) for the second switching insert and the introduction orifice (4) is so designedthat the key (6) is retained in the key rose (1), without external assistance, only in aposition having a minimum depth of introduction, in which an actuation of the furtherswitching insert is guaranteed.
