Abstract
An unloader position control switch assembly is positioned along the pivot axis of an unloader tube and is provided with a downwardly depending key that engages a slot formed in a pivot pin fixedly secured to the unloader tube. The switch assembly has two switch elements that are mechanically interconnected and are automatically resettable after the unloading tube substantially reaches either the storage position or the unloading position for the unloading tube. An operator's switch is interconnected with the control switch assembly so that an operator may easily manipulate the positioning of the unloader tube.
