I'm curious about something - why do Americans refer to a Single Pole Double Throw switch as a "3-way" switch. I know it has three terminals, but the current can only flow two ways and the switch has only two positions.
Confuses me every time as we in the UK refer to this as "two way". I guess you could call it "4-way" as there are four combinations of positions for the pair of switches!
