Abstract
Stationary contact structures for an electrical contactor include a base plate portion, a riser portion and a turnback portion. The riser portion extends substantially perpendicularly from the base plate portion and a stationary contact pad is disposed directly above the riser, reducing the occurrence of mutually opposing flux during closure of movable contacts in the device. A current carrying extension may extend beyond the riser for carrying current during steady state operation. In such case, separate current carrying paths are defined in the stationary contact for transient and steady state operation. The portions of the structure are formed by processes, such as extrusion, which permit the desired geometry to be obtained between the base plate and riser. The turnback portion may descend towards the base plate portion to introduce arcs into an elevated position in a splitter plate stack.
