Hall effect transfer case shift mechanism position sensor

A transfer case having a shift mechanism position sensor, comprising, in combination,

• an input member, a first output member and a second output member,
• at least one clutch member moveable between a first and a second position,
• a bi-directional driver for moving said clutch member between said first and said second positions,
• a structure for linking said driver and said clutch member,
• a planar member having a plurality of apertures and secured to said structure for movement therewith, and
• a plurality of Hall effect sensors disposed adjacent one side of said planar member for providing distinct combinations of binary signals corresponding to distinct positions of said plate and said structure.

A transfer case having a shift mechanism position sensor comprising, in combination,

• an input member, a first output member and a second output member,
• at least one clutch member operably associated with said input member and moveable between a first position and a second position,
• a bi-directional driver for moving said clutch member between said first and said second positions,
• a ferrous plate having an array of apertures disposed for movement with said clutch member, and
• a plurality of Hall effect sensors disposed adjacent one side of said ferrous plate for providing at least distinct combinations of binary signals corresponding to three distinct positions of said plate relative to said Hall effect sensors.
