摘要： A plurality of PNPN switches, each permitting current flow in either, i.e., positive or negative, direction, are arranged at the cross points between the rows and the columns of the speech paths so as to form a matrix. The gate trigger terminal of each PNPN switch is connected with a gating current circuit having a high impedance, which circuit is adapted to control ON and OFF operations of the switch. A plurality of means are provided to selectively turn the gate current circuits on and off so that gate current is supplied continuously for the gate terminal of any desired PNPN switch at least for the time during which the corresponding cross point of the matrix is to be electrically bridged.

摘要： A stable semiconductor switch comprising a PNPN switch, a transistor, a driving device, and diodes. The PNPN switch is composed of four-layered PNPN structure and has three PN-junctions, an anode, an anode gate, a cathode gate, and a cathode. The collector and the emitter of the transistor are connected to the cathode gate and the cathode of the PNPN switch, respectively. The driving device has its one end connected to the anode gate of the PNPN switch and its other end connected to the base of the transistor so as to drive the transistor in transient state. The diodes are connected between the driving device and the emitter of the transistor in a manner so that, when the PNPN switch is controlled to fire and a back current tends to flow through the PNPN switch temporarily, the back current does not flow through the transistor so as to prevent the transistor from causing any abnormal actions such as oscillation.
