PROBLEM TO BE SOLVED: To provide a DC relay performing repetitive motions in a compact size in a simple structure and attaining a high voltage and large current. SOLUTION: An inverted circuit is arranged in parallel with a primary contact in a DC circuit, a break of the primary contact is carried out, and circuit current is inverted in the inverted circuit using a MOS-FET as a formation element. After limiting the current, extension of contact capacity is provided by breaking a secondary contact and restraining an arc. Repetitive motions of the DC relay are achieved by using the MOS-FET as a formation element. COPYRIGHT: (C)2009,JPO&INPIT
