Abstract: A relay for high voltage and current is provided to short external power connected to both sides of a contact electrode part by bringing connecting electrodes connected to both sides of a connecting electrode fixing plate into contact with the contact electrode parts through the movement of a central axis. In a relay for high voltage and current, a connecting electrode fixing plate(30) is vertically coupled at the center of a central axis(10). Connecting electrodes(50) are coupled at both sides of the connecting electrode fixing plate. A driving unit is connected to one end of the central axis to move the central axis forward and backward. A fixing plate(20) of the contact electrode part is coupled between both ends of the central axis and the fixing plate. Contact electrode parts(40) contacted to the connecting electrodes are coupled at both sides of the fixing plate.
