One for the safety gurus...
I've been asked to design and build the controls for a hydraulic shear. It's a floor-mounted, foot-pedal operated machine using a cylinder to operate a single (upper) pivoted blade downward past a stationary lower blade. So it's a big scissors, with the point nearest the operator, who holds the part to be cut with a hand at each end. The cut speed is to be in the order of 2s from top to bottom. So long as the footswitch is pressed, the cycle will continue (down/up). If the footswitch is released, the blade returns to the top. I've found a footswitch by Bernstein that incorporates an E-stop function (push past detent), but even so, the whole thing looks like a can of the proverbials. Any thoughts?
