ABSTRACT:
A mechanical shut-off and bypass assembly for controlling operation of a wet/dry vacuum cleaner includes a switch movable between on and off positions. A toggle member is pivotably mounted with respect to the switch and is movable to operate the switch between the on and off positions. A user operated actuator mechanism engages and manipulates the toggle member to actuate the switch. An automatic shut-off mechanism engages and manipulates the toggle member, independent of the user operated actuator mechanism, to move the switch to the off position when the liquid level in the vacuum cleaner tank reaches a preset shut-off level. The user operated actuator mechanism is operable in a bypass mode, in which the toggle member is manipulated so that the switch moves to the on position, thereby counteracting the shut-off mechanism.
