Abstract
Abstract The following specification describes a multi-position switch control assembly in which a rod is mounted for universal pivoting movement, with the movement being guided by a guide plate, to operate any one of a plurality of switches selected in correspondence with the pivot direction. An axially movable detent carried by the rod is spring biased for engagement with either a central opening or recess in the guide plate when the rod is in the home position to hold the rod in that position, or with another guide plate opening or recess when the rod is operated to hold the rod and selected switch in an operated position until a positive force is applied to return the rod.

A switch control assembly for use in selecting one circuit among a plurality of circuits, the improvement comprising a support plate, a guide plate secured parallel to and spaced from said support plate with said guide plate having a central opening of one diameter communicating through respective guide slots with a plurality of circular openings of smaller diameter spaced circumferentially about said central opening, a rod extending through any one of said guide plate openings and slots, pivot means mounting said rod on said support plate for universal pivoting movement about any one of a plurality of axes lying in a plane parallel to said support plate for movement into any one of said openings and slots, a plurality of switches each individual to one of said circuits and carried on said support plate at spaced positions individual to each spaced guide plate circular opening, an actuating arm individual to said switch arranged for movement in a plane parallel to said support plate with each arm biased for tangentially engaging said rod in said central opening and moved individually by said rod against said bias in response to said rod being pivoted through a respective slot to a respective position in a respective spaced circular opening for selecting a respective circuit, a spherically shaped member of larger diameter than any of said openings and slots carried by said rod for movement therewith and arranged to move axially of said rod into partial engagement with said openings only, means biasing said member axially of said rod toward said guide plate for partial engagement in any one of said openings to hold said rod in any one of said openings against pivoting movement whereby said rod is held in said central opening in response to pivoting movement of said rod into said central opening and a selected switch arm and switch are operated and held operated in response to pivoting movement of said rod from said central opening to a respective one of said spaced openings with said one diameter central opening engaging a greater portion of said member than said smaller diameter spaced openings to require a greater force to move said rod from said central opening than from said spaced openings, and a pair of guide edges in said central opening for each slot for guiding said rod into the respective slot in response to pivoting movement of said rod in a corresponding direction.
