Abstract
An actuating device (22) operated by a hookstick (12) is attached to a manually operated fused cutout switch (10) or a oil circuit recloser switch (22). The device (22) is readily clamped to a ring (14) of the switch with a locking member (30) and a cantilever (24), each defining a boss or raised portion (34) and (60, 64, selectively for the cantilever), which bosses are disposed within the ring (14) to bear against an inner surface of the ring. A fastener (40) secures the locking member (30) and the cantilever (24) together. The hookstick (12), being engaged in the receptacle (48, 50), moves the actuating device (22) to alternatively open or close the switch. An alternate embodiment of the cantilever and a method of actuating a manually operated switch are disclosed.
