Does anybody other than Ford use this switch?
I've owned a few cars from other manufacturers, and I don't think they an inertia switch like the Fords do. I know my old Mopars didn't, and I'm pretty sure my Trans Am doesn't.
Not something I've ever thought about. I know I've had to bypass them once or twice.
My 2011 Focus has one, mounted to the passenger side kick panel.
Gm did in the early 90s but I can't remember if it was the same style switch or not. Atleast my mom's 91 rivi did when she had me change the fuel filter for her. Other than that I have no idea.
