3.4
Auto return framework
The mechanism installed in the switch which, when the handle of the turn
signal switch is in the left (L) or right (R) position, if the steering wheel returns
from the left or right position to the original position, makes the handle
automatically return to the neutral (N) position.
3.5
Speed character
The characteristics of automatic return mechanism which cancels the
steering signal when the steering wheel returns at high speed.
4 Requirements
