Abstract
A rotary shifter having a cylindrical shaped knob with an inner circumferential surface defining an open interior and exhibiting a detent profile. A stationary inner housing is positioned within an open interior of the knob and supports outwardly biased pawls establishing an interface with the detent profile in a selected rotational position. The inner housing supports a rotating spur gear having an end secured magnet positioned above a sensor incorporated into a printed circuit board (PCB), rotation of the knob resulting in the sensor to communicate to a processor component of the PCB a given rotational position designating a given shift or mode selection. The knob includes an illuminating surface for presenting menu options of the shift or mode selection.
Claims18
A rotary switch assembly, comprising:
- a housing having 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 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 including a plurality of rotational positions, with first and last mono-stable 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 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;
- angled portions configured at opposite end locations of said first and last monostable positions such that toggling of said knob in either of said end positions resulting in said microcontroller presenting subset mode depictions on said surface display;
- and
- a surface display incorporated into said knob for presenting the shifter position or mode selection.

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.
