The Palm Touch Element creates a simple interface between you and your pneumatic engraving system. With the Touch Element, you no longer depend on a foot control. Now you can have precise actuation that feels more natural.

Instead of using a foot pedal, pressure is applied to the Palm Pad (rubber end) located on the back side of the handpiece to activate. The Palm Pad can be customized for increased sensitivity. Handpiece barrel not included.
