Claims (1)

[Scope of utility model registration request] A sealed container in which mercury is stored, the container having two vertically divided chambers, an upper chamber opening at the upper end of the communicating tube and a royal chamber opening at the lower end of the communicating tube, which communicate with each other through a communicating tube. , are formed using a conductive material, are enclosed in the lower chamber insulated from each other, and are attached to the sealed container facing each other, with the sealed container having the lower chamber on the lower side and the upper chamber on the lower side. When the lower chamber is supported upwards and erected, it comes into contact with the mercury accumulated in the lower chamber, forming a current flow path between them, and when the lower chamber is supported above the upper chamber and erected, . A mercury switch comprising a plurality of electrodes that open a current flow path between them by moving the mercury in the lower chamber into the upper chamber through the communication pipe.
