ABSTRACT:
An electro-optical switching apparatus which comprises at least an input photo-emitter circuit which lights up a switching matrix comprising a plurality of switching elements selected with two pluralities of crossed connections. Under the control of switching signals one of these elements turns on and allows the light to pass through. An image of this switching matrix is formed by a lens onto a matrix of photo-receiver circuits and the light transmitted through the turned on switching element induces in one of said photo-receiver circuits a transmitted switched signal.
