ABSTRACT:
A high-voltage switch is operated by a reciprocable link. The link is reciprocated by a rotatable driven member. A rotatable drive member is rotated by a switch operator. It is desired to lock the members together for conjoint rotation after each is placed in a predetermined position, for example, when the switch is closed and the operator is in the switch-closed position. The members are intended to be locked together by a fastener which passes through a hole in each member, but normal tolerances often lead to the holes being misaligned in an unpredictable member. Accordingly, an elongated slot is formed through one member. A hole is formed through the other member. The hole is so formed as to generally overlie and encompass the slot when the members are in their predetermined positions. A disk having an off-center aperture is put in the hole and rotated until the aperture overlies and is aligned with the slot. The fastener is then inserted through the aperture and the slot to pull the disk and the members together. The members are thereby locked together for conjoint rotation.
