Provided is a hybrid switching device which can easily achieve a plurality of interruption duties demanded for a high voltage switch and has a short interruption time. The hybrid switching device comprises at least two or more switches which are connected in series, wherein one of the switches is a vacuum switch (3) comprising, in a contact portion, a vacuum valve, and one is a high-breakdown-voltage switch (5) comprising a contact portion of greater dielectric strength than the vacuum switch. The high-breakdown-voltage switch (5) and vacuum switch (3) have: support portions (8 and 18) which provide electrical insulation from a ground plane while supporting respective pressure vessels (7 and 17) which are each filled with an insulating medium and in which the respective contact portions (9 and 19) are housed; operation units (10 and 20) for driving the contact portions (9 and 19); and power supply units (11 and 21) which supply power to the respective operation units (10 and 20). Movable electrodes (37 and 56) for the respective contact portions (9 and 19) connected to the respective operation units (10 and 20) are equipotential to the respective operation units (10 and 20).
