Switching device including frame - has hole for operating element to move blocks to make contacts with set

摘要

The switching device has blocks (10) movable in the frame (2). Contacts (22) connected with the frame (2), can make contact with the blocks (10). The operating device can be inserted into the hole (8) in the frame (2) in order to move blocks (10), so that they make contacts with several contacts of the contact set (22), and open and close circuits between the contacts. A spring contact rod (14) forms the core to a spring (16), which helps each block to maintain its position in the frame. Each of the latter comprises a number of similar sections into which the blocks are inserted.
