ABSTRACT:
A space switch is disclosed which comprises an array (10) of cells (11, 13) which are interconnected with one another. The cells have a transmission gate (11) and a latch (13) for allowing a signal to pass from an input into the cell to an output from the cell. A column selector (12) and a row selector (14) are provided for selecting an appropriate one of the cells (11, 13) so that any one input to the array of cells can be coupled to any output of the cells.
