登録請求の範囲第１項に記載の切り替え装置。[Claims for Utility Model Registration] (1) A switching device 1 for switching and connecting lines between systems having different power supply systems for each of a plurality of information processing systems, wherein a circuit for the switching circuit has two volumes. A wire latching relay 120 is used, and power is supplied to each of the primary winding and secondary winding of the latching relay 120 from a power supply section within the different information processing system systems or from each of the different information processing systems. The switching instruction line for the switching control is also carried out from the different system systems mentioned above, and in the event of a failure of the information processing system that is normally operating as the operating system, the power supply is switched from the normal standby system. , a switching device characterized in that switching is performed by a switching instruction. (2) In the above switching control, a signal indicating that the switching signal for the latching relay 120 has been sequentially propagated to the group of latching relays 120 is controlled to also serve as the switching completion confirmation signal. A switching device according to claim 1 of the utility model registration claim.
