ABSTRACT:
There are three spring blades held in working relationship to a camstack which provide the making of two different and distinct circuits simultaneously by substantially simultaneously closing electrical contacts carried by the blade. Of the three blades a lower level blade engages cam contours of the camstack, a middle level blade includes a follower which engages a hub portion of the camstack, while the upper level blade extends freely above the middle blade.
