Hello fellow allaboutcircuits members, my name is Craig and I work in a mass production facility. With that in mind, i'm asking of you guys the most reliable way to press the pneumatic valve located here, actuated by a momentary foot pedal switch while leaving the valve, not the push button intact.
The normal operation of the pneumatic valve is as follows:
Applying light pressure will open valve, 4-ton hydraulic press comes down repeatedly "three times a second' until operator removes hand from valve and spring pressure returns valve to closed position. I ask the most reliable way because if the circuit were to close inadvertently while coworker was in the wrong place at the wrong time, then there would be a liability concern. There is nothing but aluminum machining taking place, the foot pedal will have to be able to withstand abuse as well.
