Abstract
A cleaner having a rectilinearly movable hand grip, movable along the axis of the cleaner handle, is provided with a switch actuator that can initiate action of a switch fixed relative to the handle and, therefore, not movable with the hand grip. The switch actuator includes a lost motion arrangement engageable over a switch button of the switch so that the switch actuator and switch remain in an engaged position independent of the axial location of the hand grip. The cleaner may be a power drive cleaner in which movement of the hand grip controls power driven movement of the cleaner. In this case, the hand grip and handle may have provision for placing the cleaner in a non-drive, neutral position.
