Abstract

In a cross-bar switch of the kind disclosed in the parent Specification 1,091,495 where a coordinate array of contact sets and co-ordinate operate bars are contained in a sealed box and movement of a bar is made by a rod which is connected to one end of the bar and which passes through an individual flexible diaphragm in the wall of the box, the present invention provides a further diaphragm in an opposite wall for each bar to which its other end is attached. Movement of the bar due to changes in pressure within the box relative to the outside are thereby avoided.
