Abstract: A conveyor system, control assembly used with the conveyor system, and method of assembling a control assembly to a member made of ferromagnetic material. The control assembly has a control housing that houses at least one control component that is adapted to perform a control function. A support mechanism supports the control housing with the member. The support mechanism includes at least one permanent magnet mounted at a surface of the control housing that is adapted to attract the housing to the ferromagnetic material and a positioning feature. The positioning feature resists movement of the housing with respect to the member. The positioning feature may be adapted to resist movement of said housing with respect to the member in at least one degrees of freedom and perhaps in at least two degrees of freedom.

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.
