<P>PROBLEM TO BE SOLVED: To keep a desirable condition of electric contact that poor contact or increase of contact resistance hardly occurs, and also to reduce wasted power consumption when electronic equipment stands by or is in nonuse. <P>SOLUTION: A device for recovering a condition of the electric contact is mounted on a slave control unit 12 which is input an electric signal SG1 from a switch SW. The device includes: a data communication section 31 for communicating between other control units and itself; a corrosion protection circuit 33 which temporarily applies large current for recovering condition to the electric contact of the switch SW; and a control section 32 which temporarily permits the corrosion protection circuit 33 to energize when the data communication section 31 receives a common signal of a header, the common signal being commonly included in the all communication signals which the data communication section receives from the other control units. <P>COPYRIGHT: (C)2012,JPO&INPIT |
