Abstract
Abstract A reversible plural motor control system includes a plurality of alternating current responsive circuits and a plurality of direct current responsive circuits with each circuit containing a separate pair of fixed and movable contacts mounted respectively on fixed and movable supports. The contacts on the moveable support comprise a first plurality of moveable contacts and a second plurality of moveable contacts insulated from the first moveable contacts, and the contacts on the fixed support comprise a first plurality of fixed contacts and a second plurality of fixed contacts insulated from the first plurality of fixed contacts. The moveable support is mounted for movement relative to the fixed support from a neural position wherein the moveable contacts are spaced from the fixed contacts to a selected on of a plurality of different operating positions in each of which a separate pair of contacts of said first and second pluralities of fixed and moveable contacts engage and a separate pair of contacts of said second plurality of fixed and moveable contacts engage.
