A disconnect switch and drive mechanism therefor particularly adapted for use in gas insulated substations. The drive mechanism comprises a pair of parallel support members having a plurality of gear teeth at one arcuate end section thereof, first and second crank members pivotally coupled to the support members and having aligned openings therein, and a connecting rod extending through the aligned openings and rotatable with respect thereto. A crank gear is rotatably coupled to the first crank element and cooperates with the gear teeth of the support member, and a rod gear is fixedly secured to the connecting rod and cooperates with the crank gear, so that upon pivotal movement of the crank elements, the support member gear teeth cause the crank gear to rotate which causes a rotation of the rod gear and the connecting rod attached thereto. A drive arm fixedly secured to the connecting rod rotates with the connecting rod. The connecting rod experiences both an arcuate and a rotational movement upon pivotal movement of the crank elements, and results in a straight line movement of the distal end of the drive arm.
