In a broadband signal space switching apparatus, respective switching elements are controlled by respective decoder-controlled, crosspoint-associated memory cell and are respectively formed with a CMOS NOR gate and a CMOS NAND gate, each of which has a respective input connected to the appertaining signal input line and another respective input connected to the output or, respectively, to the complementary output of the memory cell. The two inputs of a CMOS push-pull output circuit are connected to the output of the CMOS NAND gate and to the output of the CMOS NOR gate, the output of the CMOS push-pull output circuit forming the output of the switching element. The two source electrodes of the CMOS push-pull output circuit are fed by two feed voltage sources corresponding to the CMOS logic levels.
