摘要：The switching device comprises dollars a a) at least one mosfet - switchingelement (2) as well as of dollars a b) at least a jfet - protective element (3), which, for theswitching element is electrically connected in series and the electric current to a

maximum current (saturation current) is limited, and dollars a is c) control means (4, 5, c, r,φ 3 φ, 31), the maximum current of the jfet - protective element dollars a c1) during orafter a time delay to the switching on of the switching element to at least in the timeaverage of at least an increased value and dollars a c2) then back again to at least a lowervalue control. Dollars a advantage: higher starting - or switch-on via currents arepermitted, are again later overcurrents limited.
