What was needed was some way to connect each pair of intersecting wires in the crossbar with a switch that could be turned on and off at will 我们要做的是得在交叉杆里,每个导线交叉处连结一个开关,并且可以随意开关。

The resulting interwire junctions form a switch at each intersection between crossing wires that can hold its “ on ” or “ off ” status over time 每个导线交叉处形成的接点便成为一个开关,可以维持在开或关的状态(见右页交叉路上的开与关) 。
