For starters you have only placed a deposit and did not accept the answer although JHOOP is correct in his answer. You can request a refund of your deposit if you'd like.
There may have been a misunderstanding in the terminology. When most customers request a location or other information about an "inertia switch" they are referring to the ford standard electrical device that shuts down the fuel pump.
