Abstract
A pneumatic control system for a press which includes a pair of start switches. The system is constructed so that the press can only be started if both of the start switches are actuated within a predetermined time interval. If one of the start switches is released during a down stroke of the press, the press is stopped. A cam operated switch permits continued operation of the press after the press has reached its bottom position even though start switches are released after the press has passed full down position. A brake cam operated switch prevents operation of the press if the press fails to stop at its full up position.
