ABSTRACT:
The live insertion circuit of the present invention comprises a movable magnetic body for changing an inductance of a variable inductor, and the movable magnetic body is moved toward a supporting member by a rod at the time of inserting the package into the unit. At this time, an inductance of the variable inductor is changed according to the connection condition of terminals for connecting the package and the unit, thus suppressing a surge current.
