ABSTRACT:
In a broadband signal switching network with a switching point matrix constructed in FET technology, an input driver circuit is connected for feeding a respective matrix input line, which driver circuit is blocked via an inhibit input when a prescribed signal level is reached on the respective matrix input line which guarantees a safe switch through of the switching element connected with the matrix input line, whereby a further recharging of the matrix input line is prevented.
