ABSTRACT:
A pivotal handle for an actuator of a window includes a triangular shaped cap member with a recess along one side of the triangle shape into which the splined shaft end of the actuator is inserted and clamped. A handle member is pivotal relative to the cap member about a transverse pin positioned directly at the end of the recess. The position of the handle relative to the cap member is controlled by a spring ball mounted within the cap member which cooperates with a straight sided slot on the inner face of the handle member.
