A medical manipulator wherein a first section provided with a driven coupling is detachably attached to a second section provided with a driving coupling that includes a drive source and is driven by the drive source. The electrical switch includes a linear magnet assembly contained within a housing and movable along an axis of the housing, a rod attached to an end of the linear magnet facing an open end, and means for attaching the housing to a surface. The first and second insulating members are out of correlation one with respect to the other, such that there is at least one region in which the first electrode overlies the third electrode, and at least one other region in which the first electrode overlies the fourth electrode. Then, a profile will be created for the set of IT resources, the profile typically including information related to a service demand, a capacity, a utilization, and a performance of the set of IT resources.
