摘要

An improved phase detector ballpoint pen, essentially characterized by the fact that in the upper cap there is a stepped internal stepped stairway and stop of a tubular piece with lateral berviations, which retains at one end a pivot with a thick head, protruding from one end of the pushbutton in communication through a metal rod with a resistor, which communicates with a neon ignition bulb through a ring interposed between them, supporting the opposite end of the neon bulb in the corresponding end of the ballpoint pen charge, with insulating inner sleeve fitted at the connecting end of the upper cap with the hollow lower body in the use of the ballpoint pen, all operatively arranged so that when pressing the end of the push button, optionally protruding from the end of the pen cap according to the position of work or out of use thereof and when the tracer point comes into contact with the connecting means, whose phase is to be determined, it causes the neon bulb to light up, visible from the end through transparent windows presented by the cap of the ballpoint pen.
