The present disclosure generally relates to a field of electro-mechanical engineering.
Particularly, but not exclusively the disclosure relates to a switch assembly for a vehicle.
Further, embodiments of the disclosure relates to a rotary switch assembly for shifting the
gears of the vehicle.
BACKGROUND OF THE DISCLOSURE
Powertrain of a vehicle comprises of various parts such as an engine, a transmission
assembly, drive shaft, differentials and traction members such as wheels [rotors in case of
water vehicle and turbines in case of air vehicles]. While the engine forms the heart of any
vehicle, other components such as the transmission and other parts constitute an equal
amount of importance in a vehicle. Generally, the power of the vehicle is determined by the
amount of torque and power an engine is developing. However, all of this power needs to be
transmitted to the final drive [i.e. the wheels of the vehicle] in order to move the vehicle.
Hence, transmission assemblies and the drive shafts play an important role in putting all that
power on paper to practical use in moving the vehicle.
Conventionally, the first means of power transmission were belt and chain drives
which would transfer the power of the engine to the wheels of the vehicle. With the
development of gear and gear trains, much of the power generated from the engine was
transferred to the wheels of the vehicle.
With the advancement of transmission boxes, manual shifting of gears formed a new
era in the vehicles which helped the users shuffle between the power bands of the engine.
Moreover, manual transmissions included a shifter stick which was installed within the cabin
of the vehicle. The shifter stick was directly connected to a transmission case which upon the
action of the user within the vehicle cabin would shift the gears of the vehicle. This provided
an ease to the user in order to control the speed of the vehicle at various power bands.
Modern vehicles emanating from the 18th century saw a shift in the transmission options from
manual to automatic transmissions, wherein usage of clutch by the user was completely
eliminated. The user had to just slot in the gear lever to drive for moving forward or in
reverse direction. However, gear levers configured in the cabin of the vehicle consume
majority of the space and require additional space for the travel of the gear lever.
Additionally, the levers tend to reduce the seating space within the cabin of the vehicle.
3
With the elimination of the gear levers, the gear shifters were designed to a knob or a
paddle which was incorporated within the cabin of the vehicle. The gear shifter paddle needs
to be tapped or rotated [in case of knobs] in order to select the gear and move the vehicle.
This saw that, effort of the user was reduced by eliminating the gear shifters.
However, in many occasions, the users tend to rotate the knob with additional torque
or tap the paddle with harshness and the shifter used to slot into the wrong gear. This would
cause an irritant to the user or in some occasions cause the vehicle to go in a direction
unintended by the user. Moreover, the user upon shifting of the knob or paddle would not get
a feel if the gear has been locked in place. This, causes uncertainty as to which gear is
engaged in the vehicle.
In light of the foregoing discussion, there is a need to develop an improved rotary
switch assembly to overcome one or more limitations stated above.

Figure 5 illustrates top, front and section views of the rotary switch assembly (100),
operated in drive (D) condition according to an exemplary embodiment of the present
10
disclosure. When the user rotates the knob (20) through the third cap (48) to drive (D)
position, the at least one detent element (8) connecting the knob (20), rotates up to the axis
D’-D’. Due to the rotation of the at least one detent element (8), the at least one magnet (14)
alters the magnetic flux of one of plurality of hall-effect sensor (18). This generates a
corresponding electrical signal, which is transmitted to the transmission control unit, thereby
shifting gears to drive condition. Thus, the vehicle is operated in drive i.e. in forward
condition.
Figures 6, 7 and 8 are exemplary embodiments of the disclosure illustrating sectional,
top view and side views of the at least one detent element (8). The at least one detent element
(8) comprises of a circular ring on which plurality of crests (10a, 10b) and at least one trough

the casing (2) such that, when the knob (20) is rotatably actuated by the user, the slider pin
(22) traverses over the plurality of crests (10a, 10b) and the at least one trough (12). In an
embodiment of the present disclosure, the slider pin (22) when on the at least one trough (12)
shifts the gear position to neutral (N). In an embodiment of the present disclosure, if the slider
pin (22) traverses over the at least one crest (10b), shifts the gear position to drive (D). In an
embodiment of the present disclosure, if the slider pin (22) traverses over the at least one
crest (10a), shifts the gear position to reverse (R).

but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C
together, B and C together, and/or A, B, and C together, etc.). In those instances where a
convention analogous to "at least one of A, B, or C, etc." is used, in general such a
construction is intended in the sense one having skill in the art would understand the
convention (e.g., "a system having at least one of A, B, or C" would include but not be
limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B
