The outer ends of the travelling nut engage a pair of connecting links which rotate a pivoted roller bracket. The roller bracket carries a racking roller which engages a cam slot in a member extending from the rear portion of the cubicle or housing. The shape of the cam slot plus the increasing lever arm of the connecting links around the pivot pin on the nut provide a variable racking force which is needed for primary disconnect contact engagement.
