Abstract
A dual switch actuator mechanism for coordinated actuation of two high-current switches, each of which includes a switch operator mechanism for opening and closing the switch in response to rotation of a switch operator shaft. The switches are mounted adjacent to each other with their switch operator shafts in aligned paraxial spaced relation. The dual switch actuator mechanism includes a rotatable main shaft positioned between and in aligned paraxial relation to the switch operator shafts. A Geneva drive plate having an arcuate bearing surface is affixed to the main shaft; two drive pins are mounted on the drive plate. Two modified Geneva follower plates are provided, each affixed to one of the switch operator shafts. Each follower plate has a drive slot for receiving one of the drive pins and an arcuate bearing surface which is complementary to the drive plate bearing surface. For a given neutral position of the main shaft, each drive pin is positioned in the entrance of a follower plate drive slot and the bearing surfaces of both follower plates engage the drive plate bearing surface. Rotation of the main shaft through a predetermined angle in either direction from the neutral p…
