It is not a ground - One is a common "C" and the other two are normally open "NO" and normally closed "NC"
The hot lead goes to common then determine if you need open or closed for your other wire.

And here is the new one:

That switch that has three prongs is a normally open side and a normal closed side use an OHM meter to see positions that you need.

Swapped in the new switch and now works like a charm!

Website does show configuration. It may be marked on switch or test with meter. Check your old switch for whether it is normally open or normally closed.
Replacement should work.

Here is my switch:


And here is the new one:

The center could be the common and each end is either normally open or normally closed.
Might want to use an Ohmeter to verify configuration before installing. It should be marked on side of switch.
What is the Radio Shack number?

I could find what type of switch is in the jacks. Many places may have one if you take it with you. Graingers or Radio Shack
