Abstract

In switches of that type it is frequently necessary to safeguard that in small angular switching distances they reliable take the switching positions in which the desired indexing operations take place. The present invention uses a replaceable locking ring which through its equidistantly arranged teeth fixes the possible angular positions of the rotary switch in that at least one tooth of the support, in the different angular positions, respectively engages between the locking teeth. Advantageous developments of the invention are concerned with means to lock the switch against twisting by inadvertence in that a gate valve is to be placed in its unlocking position before the switch can be indexed by one rotating step to the next position.
