Helo - I have a GT2550 (13A-2C7P710) and last year I had to replace the PTO switch. The new one (aftermarket) worked fine but quit the other day. Upon removing it I noticed that the original (I had kept it) had 8 terminals and the new one had 7. I'm trying to find an 8 pin switch like the original with no luck. Is the 7 pin an internal redesign or am I missing something here? Thanks -

According to the IPL your switch terminal config should look like this.
The old switch you have probably looks like this one.
They can be interchange as long as you don't need the extra terminal in the second row. Most manufacture usually have the connector housing keyed on the lower row as to sure you install the connector correctly.
As long the replacement worked fine then replace with Stens 430-180 Yellow Tear Drop knob or Stens 430-396 Black Tear Drop knob. But there is a couple knob shapes out there that will work too.
Electrically the pin version works as follows. It just the 7 pin is not operating a terminal as in the connector the position is probably not having a wired connection.
