A collimated beam alignment system for aligning a receiving insulator, a guide insulator and a drive insulator of an electric power disconnect switch. The collimated beam alignment system includes an emitter stage temporarily attached to the receiving insulator, an aperture stage including an alignment aperture temporarily attached to the receiving insulator, and a target stage including an alignment target temporarily attached to the drive insulator. With the drive insulator rotated to a switch-closed position, proper alignment of the receiving insulator, the guide insulator and the drive insulator is indicated by a visible spectrum collimated beam from the emitter stage passing through the alignment aperture and illuminating the alignment target. Once the insulators are aligned, the alignment system is removed and the live components of the disconnect switch are attaches to the insulators.

An electric power disconnect switch and associated vacuum circuit interrupter with a modular, removable contactor unit housing a modular, removable vacuum bottle unit. The vacuum circuit interrupter may be mounted on a bracket adjacent to the jaws of a disconnect switch, where the blade of the disconnect switch moves the actuator arm of the vacuum circuit interrupter during operation of the disconnect switch. A technician carries a spare contactor unit to the disconnect switch location, where the technician removes and replaces the contactor unit. The vacuum circuit interrupter includes a separable connection between the drive unit housing and a contactor unit housing, which allows the contactor unit to be rotated with respect to the drive unit to unscrew the connecting rod of the contactor unit from the drive shaft of the drive unit. A replacement contactor unit is then installed and the circuit interrupter is returned to service.

A calibration joint for a three-phase electric disconnect switch includes a linkage pipe extending through a lock ring, which includes an axial guide shaft, a threaded shaft, and a self-piercing set screw securing the lock ring to the linkage pipe. The linkage pipe also extends through a clevis housing, which includes an axial joiner shaft and a clevis bracket securing the clevis housing to an operating lever of the disconnect switch. An adjustment rod extending through the axial guide shaft of the lock ring, through the axial joiner shaft of the clevis housing, and engaging with lock nuts allows axial adjustment of the clevis housing with respect to the lock ring, and thus with respect to the linkage pipe. This, in turn, allows fine adjustment of the blade and jaws of an associated phase switch with respect to the switch actuator independent of the other phase switches.

A quick-set clevis joint for a three-phase electric disconnect switch linkage includes a clevis housing having a spring chamber axially aligned and disposed around a linkage pipe extending through the clevis housing. A spring positioned within the spring chamber provides play in the linkage. First and second thrust disks compress the spring in a first axial direction with the first thrust disk pushed against a first spring chamber end wall when the linkage pipe moves in the first axial direction while the clevis housing is blocked from moving in the first axial direction. In addition. the first and second thrust disks compress the spring in the second axial direction with the second thrust disk pushed against the second spring chamber end wall when the linkage pipe moves in the second axial direction while the clevis housing is blocked from moving in the second axial direction.
