ング手段。[Claims for Utility Model Registration] (1) There are normally-off, voltage-driven first and second switching means whose reverse bias voltages have opposite polarities, and the former has negative polarity. Sometimes, two non-controllable switches are connected in series from the former control terminal to the latter control terminal, one resistor or constant current means is connected in parallel to each of the non-controllable switches, and each of the control terminals is connected in parallel. A three-terminal switching means characterized in that a pair of main terminals are connected together as drive terminals. (2) When there are normally-off, voltage-driven first and second switching means whose reverse bias voltages have opposite polarities, and when the polarity of the former is negative, the voltage from the control terminal of the former is Two non-controllable switches were connected in series facing the latter control terminal, a resistor or constant current means was connected between both control terminals, and the pair of main terminals were connected together as drive terminals along with each control terminal. A three-terminal switching means characterized by:
