ABSTRACT:
A multi-position switch includes a movable actuator rod projecting from one end of a housing and having a cylindrical contactor disc within the housing displaceable into a plurality of radial positions to actuate a selected one or a selected pair of circuits as the contactor engages and radially deflects adjacent ones of a plurality of resilient contacts arranged concentrically about the actuator rod. The displacement of the rod and its disc is regulated by an encircling control element provided with alternate radial crests and valleys. Groups of adjacent contacts are electrically joined in series such that displacement of the disc into a control element valley axially aligned with any one group of contacts closes one circuit while displacement into either adjacent control element valley closes an alternate circuit involving two adjacent series of contacts. An additional circuit is regulated by either of two means including the axial depression of a handle on the actuator rod to close a circuit through the rod, handle and housing of the switch or alternatively, by means of a trigger mounted exteriorly of the housing and selectively closing a separate contact switch assembly attached to the housing.
