contacts when a visit back showed that there were two rows of three
) and poor typing (I wrote there were four
rows when, in reality there were only two
rows), I described the switch quite incorrectly. Instead of saying "four rows of four contacts each" I should have said that there were "two rows of three contacts each."
I now understand that "two rows of three contacts" describes a double-pole double-throw switch which is commonly (but not exclusively) used as a phase reversal switch in ceiling fans.
