Switching mechanism for automotive heating and air conditioning systems

Image Number 5 for United States Patent #4758702.

The mechanism comprises a blower speed control lever for operating at least one electrical switch, supported by a mounting bracket which has a place for a second switch. The speed control lever has rearwardly facing rocker shaft elements which are pressed against forwardly facing semicircular bearing recesses on the switch mounting bracket. The pressure is developed by flexible flanges which project rearwardly from a mounting panel and are engageable with forwardly facing tapered shaft elements on the speed control switch. The flanges are flexed to produce a spring action. Additional guard flanges project rearwardly from the panel, into adjacent relation with additional shaft elements on the speed control lever.
