摘要： PURPOSE:To secure the channel control with no cross by selecting the channel between the driving unit and each switch grid via the bus selection relay and sharing the bus selection relay among the switch grids to receive the complex selection to secure a simultaneous selection for the corresponding driving units. CONSTITUTION:The selective driving is given to bus selection relay R12 via the bus selection relay driving circuits arranged into a matrix form, and the contact r12 selects the driving paths for switch grids 1 and 2 at one time. And when one of horizontal driving units HDV10-HDV1m plus one of the corresponding horizontal driving units HDV20-HDV2m are driven at one time, the same level is released for grids 1 and 2. After this, either one of vertical path driving units VDV10- VDV1n plus VDV20-VDV2n is driven in corresponding to the channel to be connected to open the intersection with the horizontal level. As a result, no cross is caused even with the release across the channel to carry out the channel control.
