Abstract: A multi-directional compliant shifting mechanism for a multi-speed power tool may couple a movable selector to a power transmission system of the tool, for selecting an operational speed of the multi-speed power tool. The complaint shifting mechanism may provide shifting compliance in a first direction in response to movement of the selector in a first direction, and may provide shifting compliance in a second direction in response to movement of the selector in a second direction. In one example, this multi-directional shifting compliance may be provided by interaction of the selector with a camming surface, in combination with a single compression spring. In another example, this multi-directional shifting compliance may be provided by first and second springs, selectively acting to provide compliance in the first and second directions.

Abstract: A compliant shifting mechanism for a power tool includes a selector, a first shift plate rotatable in response to rotation of the selector, a second shift plate rotatable in response to rotation of the first shift plate, a shift member moveable in response to rotation of the second shift plate to shift between a first mode of operation and a second mode of operation, a first torsion spring coupled to the first shift plate, and a second torsion spring coupled to the second shift plate. In response to rotation of the selector in a first direction, the first torsion spring may bias the first shift plate in the first direction for shifting compliance in the first direction. In response to rotation of the selector in an opposite second direction, the second torsion spring may bias the second shift plate in the second direction for shifting compliance in the second direction.
