----- 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
