Inertial Cutout Switches

[/\/\j17]

Hi,
Question for the kit car builders out there (or anyone else who knows).

I'm converting a car for fuel injection and have picked up a fuel pump inertial cutout switch off of eBay. Can anyone tell me if these have to go a specific way up - button vertical or horizontal/does it not matter/does it depend on the switch?

Cheers,

Everyone that I've seen on Fords, Jaguars and Land Rovers has been mounted on the vertical with the reset button facing up, there must be a reason for it.


Ooh, I found the instructions for Smart Racings inertia switch and it says to mount vertically or it could trigger when you don't want it to:

Hope that helps...

My TVR has one and the button faces up - vertically.

with the button pushed in.

Most will be vertical with button up but it may also need to be facing the correct way with respect to direction of travel. Is there no makers name or other markings.

Seems to be the one favoured by Rover and used in the Mini/200/.../Land Rover mounted button-up.

Anyone know if it's normally wing or bulkhead mounted (would give me orientation).

Land Rover normally mounts them on the engine bulkhead under the bonnet, Jaguar on either the drivers or passengers kick panel with an access hole for the reset button through the trim panel, newer Fords- same as Jag, older Fords- sometimes on the driver's side inner wing panel in the boot. Not sure about Mini or the rest.

Inside the vehicle where there is less chance of moisture getting to it is preferred, but make sure it's in a spot where it won't get banged buy luggage, etc.

To avoid the uncertainty of what you have and which way round to fit it I would go get one from the breakers then you can mark it before you take it off.
Put the other one back on the bay.

Inertia switches have 360 degree sensitivity there is no need to mount them with a certain side in the direction of travel. I think you are confusing them with a front airbag crash sensor which does have to be orientated with the proper end in the direction of travel....
