I am trying to figure out how this fan worked and I am lost. The four wire
switch had red power and the black common both connected to it. Why?

Also the other two connections on the switch went to the two caps. The
other
side of the caps were connected and went to the fan. Does that make sense?

Additionally, in several positions of the switch, the red and black wire
terminals are connected together inside the switch. I know that makes no
sense and it would trip a circuit breaker, but the breaker does not trip.

Disconnect the switch from the fan and the caps completely and then use
an ohm meter to probe its connections. I think you're being fooled by the
motor windings.

mine is not spst. mine has both power wires connecting to it. Then the two
remaining switch connections join and feed the motor. I still do not
understand this.

What I am saying is two wires in and one out.
