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.
