Abstract
A multifunction switching arrangement for an electronic transmission control which includes a button on a knob casing which can be moved in opposite circumferential directions and alternatively operates two switches in the assemblage which in turn causes an upshift or downshift of the transmission. When a button is advanced in an axial direction, a third switch is operated to activate or deactivate the transmission overdrive. in one embodiment only a single button is moved to operate all three switches, while in two other embodiments a separate push button in the end of the knob casing is used to control the third switch.
Claims12
In combination, a multifunctional switching arrangement mounted to a knob casing attached at one end to a lever adapted to be mounted to a steering column, said switching arrangement comprised of a single switch assemblage having at least two switches mounted within said knob casing, a pivotal rocker button accessible from the exterior of said knob casing drivingly engaging said two switches to so as to enable each of said two switches to be selectively operated by pivoting movement of said rocker button in either direction;
- said knob casing having an opening formed therein;
- said rocker button having a body portion insertable into said knob casing opening, said body portion further having pivot retention features snap fit to pivot retention features on said knob casing adjacent said opening upon insertion of said body portion into said opening to retain said rocker button therein and provide a pivotal mount therefore.
