A complex type switch which is capable of easily achieving a plurality of current breaking performance needed for a high-voltage switch, and which has a short current breaking time is provided. A complex type switch includes at least two switches connected in series. One switch is a vacuum switch 3 with a vacuum valve that includes contact part. One switch is a high-voltage resistant switch 5 includes a contact part that has a dielectric strength larger than the vacuum switch. The high-voltage resistant switch 5 and the vacuum switch 3 include supports 8, 18 maintaining an electrical insulation to a ground while supporting pressure containers 7, 17, in which t contact parts 9, 19 are placed. Movable electrodes 37, 56 of the contact parts 9, 19 connected to the actuation units 10, 20 are in equipotential. |
