ABSTRACT:
Broadband signal switching equipment in a switching point matrix having matrix input lines connected via switching element couples, to matrix output lines having respectively two signal conductors. The two signal conductors are connected with signal inputs of a differential amplifier with a trigger characteristic. The two signal conductors of each matrix output line are connected with the operating potential source via a respective precharge transistor. The switching element couples respectively have two auxiliary transistors of different channel types, which are connected by their control electrode to the only signal conductor of the appertaining matrix input line and which form a series connection respectively with one switch transistor preferably of the same channel type. The output terminals of successive switching elements of a matrix output line are respectively connected to the signal conductors thereof in an alternating fashion.
