A "three way" switch is a SPDT switch used in pairs to switch a
device from 2 different locations.

Have never seen a center off SPDT switch in paddle or decora in
Canada the odd momemtary contact (click one way for on and one way
for off for low voltage remote control - or this one:
Single-Pole-Double-Throw-Center-Off-Momentary-Contact

There is a leviton constant-contact (not momentary contact) center off
and like I said home despot US has them ($50 - $60 if I recall).

can't think offhand where one would use one in a house - - - -

I wanted to control an attic fan. I wanted 3 options: Off, On, and
Auto. Auto means the fan is controlled by the thermostat in the attic.
A SPDT with center off would do this, but none are available. I ended
up using one of those double switches (2 SPST single-gang). Available
in paddle and decora, and relatively cheap (I think $17).
Generally that would be accomplished using a bat-handle type switch
supplied by the fan manufacturer or the control manufacturer - but 2
switches in parallel would do the job too
