ABSTRACT:
An improved handle assembly for actuating an automotive turn signal switch, a windshield wiper switch and a wash fluid switch is provided. The handle assembly includes an internal shaft, an outer tubular member and a housing. The housing is supported or the turn signal switch and houses the windshield wiper switch and the wash fluid switch. The internal shaft extends into the housing to engage and actuate either the wiper switch or the wash fluid switch. The outer tubular member is concentrically disposed about the internal shaft, and a portion of the outer tubular member extends into the housing and engages the switch not engaged by the internal shaft. Both the wash fluid switch and the wiper switch can be independently actuated by independently axially rotating the internal shaft or the outer tubular member. The turn signal switch is actuated by pivoting the internal shaft which in turn pivots the housing supported on the turn signal switch. In order to reduce the amount of lash between the internal shaft and the housing, a separate member having a load bearing surface is provided to directly engage the internal shaft.
