In today's computer world, many low-voltage data lines typically connect the host computer to various peripheral devices.

Currently, a multi-stage rotary switch device is installed to connect the upper computer to various peripheral devices. In a typical application, three input data lines connected from the host computer to the switch units are connected to each of the g stages of rotary switch units, thus providing two input lines. Similarly, for each peripheral device, three output data lines y are connected to each of the 2g stage rotary switch devices, so a total of 244 data lines from the host computer are connected through the rotary switch devices 7. , can be selectively connected in an electrical circuit to one of a plurality of sets of output data lines, thereby allowing specific peripheral devices to be linked to a host computer through the rotary switch device 7. . As the number of peripheral devices to be selected by a rotary switch device increases, the complexity of the fixed contact pattern for each role of the rotary switch device, the complexity of the movable contact structure of the rotary switch device, or both. Both increase dramatically.

Recent trends in the computer industry are that the number of data line sets will increase from 2 Da per set to perhaps even the first QG lines. This would necessarily exacerbate the complexity of prior art rotary switch devices; such rotary switch devices would be expensive to manufacture and difficult to assemble and connect in a suitable circuit configuration. It is difficult to do so.

The present invention provides an inexpensive, reliable, and easily assembled and interconnectable solution to the above-mentioned drawbacks of rotary switch devices for data line switching functions! provide, but

Each of the output devices 32.34t, El, 1.3g is normally associated with one of the output contact sets 32.34t, El, 1.3g. Electrical connections are made between the appropriate output device, e.g., one, and the associated set of output contacts by devices (not shown) well known in the art, such as printed circuit conductive paths and the like.

Supported on the common contact carrier lt is a bridge contact set. The number of internal and external multiple members of each common contact set RO, C, 3θ, each output contact set 3-1341, 8.3t, and bridge contact set V is all equal. Indicated. However, in practice, the number of inner and outer layers of each set of members will be equal to the number of data lines (eg, 41) in the computer system in which the invention is employed. Fixed contact pattern here, common contact carrier/6, and bridge contact cellar) 41θ is the connection point, common contact carrier/6 in the center of 2
When AY is rotated, the bridge contact is set! The various members of rO are arranged such that they can be selectively electrically connected to separate members 71 of the selected common contact set and to separate members of the selected output contact set. For example, common contact carrier 16! (Move it to the operating position and close the bridge contact)
Through the 30 individual members, separate electrical continuity connections between the individual members of the common contact set 20 and the individual members of the output contact set 36 can be made.

For example, the input device UO is connected in such a manner that each member of the common contact set 8 can be electrically accessed individually, so that the individual members of the common contact set 2g and the output contact set 3
By locating the common contact carrier/A'lff in electrical communication with the individual members of A, an output device such as output device D can be connected, for example, to the two separate members of the output contact set 36 individually KJf!
