Zusammenfassung:The drive mechanism for a h.v. switch includes a motor (3) with a right angle drive on its output shaft, driving a spindle with a drive worm (13) mounted on it. This rotates a worm wheel (14) about a bearing spindle (6) which rotates on arm outside the housing controlling the switching members. As the worm wheel rotates, a pin (10) projecting from its face, near the periphery, travels in a T shaped slot (12) in a heart-shaped actuator cam (11) on the face of the wheel. The pin can carry a roller which travels in the slot. The wheel also carries two further pins which project from its face to operate a switching member (17) incorporating two slots (19, 20) so as to control an auxiliary switching system.
