Switch filler

Filling systems

This is how the filling system adopted by the Pilot for its Super line is called, by the shape of the knob that activates filling. As can be seen from the relevant patent (nº US-2871825), this is a system based on the same principle as the button filler, in which a I-bar is flexed by actuating a sort of switch at the bottom of the pen. The system is very similar to the end lever filler of the Aurora, in particular to the variant with ball used on the Superna; unlike this, however, the operation is done by removing the shaft of the pen to access the internal mechanism.
