ABSTRACT:
A collision detection sensor for a waterjet system provides a signal in the event the device approaches to within a selected distance of an obstruction in the plane of the working surface. An annular pressure switch lying in a first plane provides the signal when radial pressure is applied to a perimeter of the pressure switch via an annular trigger skirt, the trigger skirt applying the radial pressure in response to a collision of the device with an obstacle.
