We've heard of that part breaking before - it's a metal bar, eh, which is located between the lock cylinder and the switch, and which causes the switch to rotate. Unfortunately, I can't remember anybody ever getting back to us to let us know if it's included with a new cylinder or with a new switch. My guess is it will be part of a replacement lock cylinder. It would be worth using the 'Search this forum' feature at the top of the Escort index page, because maybe somebody did tell us and I've just forgotten.
This is Ford's procedure for removing and replacing the lock cylinder on the '95, which should be very similar to your '94. At the part where they say to cut two slots with a chisel, you might be able to do that with a junior hacksaw blade instead.
