Switch structure

DETAILED DESCRIPTION The invention claimed is: 1.
A switch structure comprising: a case having an apertured face wall; electrical contacts mounted on said case; an indicia-carrying wheel having a plurality of indicia appearing around the rim of said wheel, said wheel being mounted for rotation in said case behind said aperture in order to present to view a selected indicium; switch means mounted in said case adapted to selectively contact said electrical contacts as said means is rotated, thereby completing different electrical circuits in various switch positions; a lever protruding through said aperture and being adapted to operate said switch means; and conversion means for rotating said wheel through a first angle as said lever is rotated through a second angle, said first angle being substantially larger than said second angle, said conversion means including means interconnecting said wheel and said lever for rotating said wheel clockwise about its axis when said lever rotates clockwise about its axis and for rotating said wheel counterclockwise about its axis when said lever rotates counterclockwise about its axis.
2.
In a switch structure the combination of: a case having first and second apertures in the face wall of the case; means defining a sealed electrical parts chamber; electrical contacts mounted on the case in the sealed chamber; an indicia-carrying wheel having a plurality of indicia appearing around the rim of said wheel, said wheel being mounted for rotation in the case behind said first aperture in order to present to view selected indicium; switch means mounted on the case in the sealed chamber adapted to selectively contact electrical contacts as said means is rotated, thereby completing any one of a plurality of different electrical circuits; a lever protruding through said second aperture and being adapted to operate the switch means; and conversion means for rotating the wheel through a first angle as the lever is rotated through a second angle, said first angle being substantially larger than said second angle
