Title: inertia switch
Post by: revolutionary on March 23, 2010, 07:33:12 PM

Hey if anyone needs one I hit the junk yard and picked up a bunch with pigtails.  I have two left - if you need one please let me know asap and I'll get it in the mail.

OR if you like the yards, just find the trunk of about any mid 90's or newer ford sedan and you can remove it with either a 5.5mm or 10mm socket depending on the car.

I might go to the yard just to use my 5.5mm socket :-D

Inertia switch is not the only option. I'm opting for the oil pressure cut out. Higher current rating

A Higher Current rating would mean better than a prior rating ???

Ok I am just having fun,,,,, :cheers: :cheers:

If you are using a relay on your pump I would wire an inertia switch between the relay and dash on/of switch. I wonder how the inspectors are going to test them?

Eric-- for a guy trained in watch repair, a 20 lb hammer seems a bit of overkill. That hammer would have bent my old Spridget in half. Can't wait to see you and Steve swing those things at something I don't own! See y'all soon.

Lets see how many ways to test an inertia switch .We can hit it  drop it shoot at it . Heck this could be fun. See you in two weeks.

I just picked up 2 this weekend and put one in the Truck(gotta have a spare!). Thanks to this thread I was reminded I hadn't done that yet.

Now the interesting thing is the one I took out of a Lincoln took a 5.5MM socket, and were bolts. The one in the Taurus next to it took a 1/4" socket and were sheet metal screws. Note keep the mounting bolt's/screws.

I tested mine before mounting it in it's final resting place. :-D

IMHO I think an oil pressure switch in addition to an inertia switch, would work.
 I don't know whose, but on youtube there is a video of a lakester rolling. After it stopped moving, it kept running for what seemed like a very long time. All the time running, with a leak, could have been spraying a large amount of fuel.
On Ford cars, the inertia switch controls a relay. I'm wiring in a 50 amp relay for ignition and fuel pump. It just might save some expensive engine repairs.
The inertia switch, from what I can tell, is bi-directional, front to rear only. No sideways or vertical trip, so needs to be installed in the same orientation as on the original vehicle.

Just my $.02

I have a Ford unit on mine and I'll have a spare with me if someone needs it.  It seems to work no matter where I smack it - I don't think the spring knows from where it's hit.  It does, however, need to be installed button UP.

Smart Racing Products offers a race car version for what it's worth.  Their website has installation tips.
