Rotary selector knob with graphical display

A rotary switch assembly, comprising:

• a housing having a cylindrical cross sectional shape, a pair of apertures in said housing revealing an outwardly projecting pair of spring loaded pawls supported by said housing, a window being configured in a further location of said housing;
• a rotatable knob having an inner cylindrical surface supported over said housing, said knob including each of an upper detent profile opposing said pawl and a lower gear profile;
• said detent profile further comprising a plurality of rotational positions, with first and last located mono-stable adjustable positions, angled portions configured at opposite end locations of each of said first and last monostable adjustable positions;
• a spur gear having a shaft rotatably supported within said housing so that a portion of an exteriorly teethed head projects from said window in meshing engagement with said lower gear profile;
• a magnet supported upon an end of said spur gear and arranged in proximity to a sensor incorporated into a printed circuit board integrated into a bottom of said housing, rotation of said knob between said rotational positions causing said sensor to read a given rotational position of said knob and, upon outputting a signal to a microprocessor component, designating any of a shifter position or mode selection, toggling of said knob in either of said monostable end positions resulting in said microcontroller presenting subset mode depictions on said surface display;
• and
• a surface display incorporated into said rotatable knob, a harness extending from said surface display and terminating in a connector in communication with said printed circuit board for presenting the shifter position or mode selection.

A rotary switch assembly, comprising:

• a housing have a cylindrical cross sectional shape, an aperture in said housing revealing an outwardly projecting and spring loaded pawl supported by said housing, a window being configured in a further location of said housing;
• a rotatable knob having a lower portion with an inner cylindrical surface supported over said housing and including each of an upper detent profile opposing said pawl and a lower gear profile, said knob further having an upper portion attachable over said lower portion;
• a spur gear having a shaft rotatably supported within said housing so that a portion of an exteriorly teethed head projects from said window in meshing engagement with said lower gear profile;
• a magnet supported upon an end of said spur gear and arranged in proximity to a sensor incorporated into a printed circuit board integrated into a bottom of said housing, rotation of said knob causing said sensor to read a given rotational position of said knob and, upon outputting a signal to a microprocessor component, designating any of a shifter position or mode selection;
• said detent profile further providing 360° rotational adjustability of said knob;
• and
• a surface display incorporated into said upper portion of said rotatable knob, a harness extending from said surface display and terminating in a connector in communication with said printed circuit board for presenting the shifter position or mode selection.
