Abstract
Abstract A multi-directional switch which is utilized for completing selected ones of a number of different electrical circuits is placed in a housing in which the different electrical circuits to be controlled terminate in pairs of spaced-apart conductors located in the bottom of the housing. A cylindrical pushbutton actuating member extends upwardly through a circular opening in the top of the housing. This actuating member has a flange on the lower end which extends radially outwardly from the main body of the actuating member, and this flange is supported on a deformable support which has a circular opening in the center. A ball bearing is placed in the opening the deformable support and engages the bottom of the housing and the bottom of the actuating member. Conductive contacts are placed on the lower side of the deformable support in registry with the various contact pairs; so that when the actuating member is tilted over a selected contact pair, the corresponding conductive contact completes an electrical circuit across the contact pair selected by the direction of tilting the actuating member.
