Here is a good explanation of the principle (3rd paragraph) and how to do it.

Hi Phillip and Graeme,

I wouldn't recommend you do this, it raises the mass of the headshell
by some considerable degree (the switch probably weighs more than the
headshell) and this is not a good idea at all.  Far better to place
the switch further down the line.



----- actually it is a good idea. It enables the reversal of polarity of
the  floating (non-grounded) coil in a stereo pickup, thereby enabling
summing to  vertical instead of horizontal. I have used it for 30+ years,
only, precisely  because of the mass you mention, Graeme, mine is a
switch I obtained from a  company that manufactures hearing aids, with no
metal, except for switch  blades and contact points (gold, rather than
silver).  The rest is plastic.  Soldering needed precision work. I did
not have a preamplifier that permitted  doing reversal at the time.

Kind regards,


George
