Ford Inertia Switch

I'm considering installing an inertia switch (Ford F2AB-9341-AA) in my fuel pump circuit. Does anyone know what the current rating is for these switches? If they are only low current, I'll use a relay. If they can handle a few amps, I'll just wire it in series with the fuel pump. I just need to know how much current they are rated for, if anyone happens to know. Thanks.

Part shows to be for a 92 crown vic/marquis.
They used the inertia switch in the actual power feed to the pump, not with a relay. I have seen the inertia switch used to control the relay coil on mustangs, not sure why. But the part number would be different. Not sure if it would be a lighter set of contacts on the pony car part verses the one you have.
You should be fine to use it in the power feed to your pump.

Thank you for your reply. I got three of these at the local U-Pull-It, one from a Ford Ranger, and two from Explorers, and they all had the identical part number. Looks like I can skip the relay.

Seems like a simple way to add a bit of a safety factor in the event of a collision. Maybe overkill, but Ford must have thought it was a worthwhile idea.

Federal regs.

Federal regulations specify how much fuel can leak after a test crash. turning off the electrical fuel pump is a good idea. Remember the original ALA KART Fire.

It just seems like overkill to me. But what the heck, if you are running an electric pump anyway it's easy enough. There are other ways too, like having it running thru an oil pressure sensor so when the engine isn't running the fuel pump isn't either, there are cars made that solve the problem that way.

Just be sure to have that inertia switch in the same exact attitude as it was on the car you took it off of.

Just finished installing the switch. Hopefully it will never be needed, but who knows?

I put one of these things in my 59.
Wired it to the ground circuit of the relay.

Ignition power to the relay coil >>>>>>>>relay coil to Taurus inertia switch>>>>>>inertia switch to ground

I would be worried I'll crash and not be able to make a quick getaway.
