Abstract

A switch coupling assembly for coupling at least a pair of switches having respective spaced apart actuator handles is provided in order to permit simultaneous switching of the separate switches. Generally tubular spacers fit between each pair of switch handles. At least one tubular spacer is dimensioned with sufficient clearance so that one end of the spacer abuts one of the switch handles while the other end of the spacer is spaced apart from the other switch handle. The switch handles are each provided with alignable openings and a tie rod is dimensioned to extend through the aligned openings in the switch handles and the spacers to couple the switch handles together. The tie rod has a groove alignable in the clearance between the spacer and the adjacent switch handle. A snap ring snugly fits in the clearance to hold the spacer in position and engages the groove on the tie rod to prevent relative movement of the tie rod. The switch handles are thereby coupled together to enable simultaneous movement of the handles.

Dependent claims

A switch coupling assembly comprising:

(A) at least a pair of switch means held together in side by side arrangement, each switch means having a switch handle movable relative to the switch means for actuating the respective switch means, the switch means being oriented so that the switch handles may move in spaced apart essentially similar parallel paths of movement, the switch handles having respective openings therethrough alignable along an axis generally perpendicular to the parallel paths of movement when the handles are moved to essentially similar positions along the respective parallel paths of movement;
(B) generally tubular spacers dimensioned to fit between each pair of spaced apart switch handles, one of the spacers dimensioned to fit between a pair of said handles with predetermined clearance between said spacer and an adjacent one of said switch handles;
(C) a tie rod dimensioned to extend through the spacers and the openings in said switch handles, said tie rod having a groove located for alignment in the clearance between said spacer and said adjacent switch handle;
and
(D) a retainer dimensioned to snugly fit in the predetermined clearance to snugly hold the retainer and spacer in position between said pair of switch handles and to engage said groove on the tie rod to hold the tie rod in position so that the switch handles are coupled together for simultaneous movement.
