The True Dwell Switch is part of the Hot Stamping Machine Safety System.
The switch should be made when the print head is 1/4 inch or less above
the part to be printed. When the machine is cycled by the safety Palm Buttons
the Printing Head starts down. If the operator removes either hand from the
Safety Buttons the Print Head should return to it's up position. If the Print Head
gets down far enough to make the True Dwell Switch the print head will stay
down for the time set op the print timer then move back to the up position. If the
True Dwell Switch is set too high the machine is not safe. The operator may be
able to cycle the machine reach under the print head while it is still moving down.
