High-speed closing switch in power distributor

PURPOSE: A high speed inputting switch of a device is provided form effective damper performance of a location control in a final location of a moving unit by using an insulating gas within a case and a structural shape of a high speed inputting switch. CONSTITUTION: A first electrode(10) includes a penetration hole. A second electrode(20) includes a accepting groove(24) which is opposite with the penetration hole. An operating contact point member(30) includes a cylindrical body(31) accepted in the penetration hole and a flange part(33) formed on one end of the cylindrical body. A closing coil(80) supplies a repulsive power to the operating contact point member. A damping hole(90) is formed on the accepting groove of the second electrode. The operating contact point material is put inside of the accepting groove by the repulsive power of the closing coil. A release coil(70) is wound on one side of the first electrode. The release coil supplies the repulsive power to the operating contact point member.
