PROBLEM TO BE SOLVED: To provide a relay device convenient to handle having a simple structure capable of accomplishing the miniaturization and reduction of weight, and cutting off a D.C. high voltage in a short time. SOLUTION: A plurality of fixed contacts 2 and a plurality of moving contacts 3 are disposed oppositely to each other in a case 1; the moving contacts 3 are supported by a contact displacement mechanism 4; and it is displaced by a solenoid 6 to open and close the respective fixed contacts 2 and the respective moving contacts 3. A series circuit is formed when the plurality of contacts 2 and 3 are electrically connected; and the generation of arcs between the respective contacts 2 and 3 is restrained by voltage dividing. This very compact relay device capable of extinguishing the arc without the need to form the periphery of each contact into an airtight structure and without securing a large extension amount of the arc, shaped into a single package and convenient to handle can be provided.
