Switch for solid insulated switchgear

A switch for a solid insulated switchgear having a common actuator that provides a driving force for switching a circuit, the switch comprising:

• an enclosure that is solid insulated and includes an electric power source side bushing portion for burying an electric power source side connection conductor, an electric load side bushing portion for burying an electric load side connection conductor, and an accommodation body portion having air filled therein;
• a main circuit switch installed, for each pole, at the enclosure, connected to the common actuator and the electric power source side connection conductor, and having a vacuum interrupter that switches an electric power circuit between an electric power source and an electric load, by receiving a switching driving force from the common actuator;
• and
• an earth switch installed, for each pole, in the accommodation body portion of the enclosure so as to be air-insulated, and the earth switch including a first fixed contactor to be earthed;
• a second fixed contactor electrically connected to the electric power source side connection conductor;
• and a movable blade connected to the common actuator, and movable to a first position for contacting the first fixed contactor and to a second position for contacting the second fixed contactor, by a switching driving force from the common actuator.
