Abstract
A press control system in which multiple pushbuttons are employed for initiating a press cycle with each pushbutton including a normally closed and a normally open blade and with each switch blade having connected in parallel therewith a monitoring circuit which produces logic signals in conformity with the position of the respective switch blade. A logic circuit analyzes the logic signals from the several monitoring circuits and permits operation of the press only when all of the switches operate properly during a press cycle.
