No, that's not confusing enough.

We call the (one or more) switches between three-ways for additional control locations "4-way switches". They do, indeed, have four terminals, and are actually DPDT switches with crossover jumpers, rendering them reversing switches.

I guess we don't have any 2-way switches; the closest we come is double-pole switches, which again have four terminals. Yikes!
