Abstract

PURPOSE:To eliminate the detachment of the incoming connector of the secondary switch by closing the link connected to the outgoing-side connector terminal of the primary switch and then opening the residual link of the secondary switch connected to the first mentioned link. CONSTITUTION:Primary switches P0 - P7 are stored in grid GPO, and secondary switches S0 - S7 are stored in grid GSO respectively. In case the multiple connection is given to outgoing connector CO, the link connected to CO is first closed. At the same time, the cross point of switch SO connected to the closed link is opened. Then connector CO is cut off from grid GPO, and the outgoing line of the extended primary switch is multi-connected to connector CO with connected incoming connectors C4 - C7 of grid GSO. After this, connector CO is connected to gird GPO, and the closed link is opened. As a result, the incoming connector of the secondary switch is not required to be detached from the grid, thus simplifying the extension construction working. Thus, a highly economical link can be constituted wit the enhanced packing performance.
