ABSTRACT:
The present invention provides a clutch-coupled crossarm mounted switch operator. The switch operator of the invention includes rotational motor means, a non-positive contact or infinite engagement clutch mechanism, and an output coupling. The rotational motor means further includes an input shaft to which the clutch mechanism is coupled. The infinite engagement clutch mechanism does not depend on rotational alignment means for engagement of the clutch. The clutch further includes an output shaft to which the output coupling is coupled. The output coupling is in turn coupled to a gang operated switch element that causes the switch contacts of the gang operated switch to open and close. Use of the clutch coupled switch operator thus effects the opening and closing of the gang operated switch contacts. Further, disengagement of the clutch mechanism allows the user to exercise and test the rotational motor means without displacing the contacts of the gang operated overhead high voltage air switch. Furthermore, the present invention includes means to manually operate gang-operated switches.
