Geofftaylor Posted January 13, 2020 Report Share Posted January 13, 2020 Some years ago I fitted an electric pump on my 3A but have never fitted a fuel cut off inertia switch. I am now thinking I should. Does anyone have any recommendations as to what switch is best suited? Quote Link to post Share on other sites
harlequin Posted January 13, 2020 Report Share Posted January 13, 2020 Vist to a scrapyard with a pair of wire cutters, get as much wire as you can. Ford Focus switch is a good option as its mounted on the side of the passenger foot footwell away from the elements George Quote Link to post Share on other sites
Geofftaylor Posted January 13, 2020 Author Report Share Posted January 13, 2020 Thanks George, By coincidence I was actually looking and wondering if a Ford Focus unit might do the trick. Geoff Quote Link to post Share on other sites
harlequin Posted January 13, 2020 Report Share Posted January 13, 2020 It's what I use on my TR6, I think I paid a fiver for it from the local scrap yard. Make sure that you get the wiring plug with some wire to make the connection to your car George Quote Link to post Share on other sites
Fireman049 Posted January 13, 2020 Report Share Posted January 13, 2020 Hi Geoff ~ I fitted my fuel pump cut-off switch under the dash near the steering column on my 3A. This allows me to 'knock-off' the switch when I park the car for extra security. In this position it's easier to re-set the switch if it operates under driving conditions. Tom.

trchris Posted January 13, 2020 Report Share Posted January 13, 2020 Peugeot 206 also uses a inertia cut off switch if you search inertia fuel switch on ebay you will find plenty its where I found one last year from memory about a tenner Chris Quote Link to post Share on other sites
Fireman049 Posted January 13, 2020 Report Share Posted January 13, 2020 I believe that my Inertia Switch came from a Rover. It cost me £6.00p. I'll attach a photo. tomorrow. Tom. Quote Link to post Share on other sites
Hamish Posted January 13, 2020 Report Share Posted January 13, 2020 I used this style. Land Rover I think https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F184103217543 But I think Toms idea of having it to hand to reset whilst driving is a good idea. that I think I’ll do.

Steves_TR6 Posted January 13, 2020 Report Share Posted January 13, 2020 I have that same rover switch, installed in original location. no issues in 2 or 3 years steve Quote Link to post Share on other sites

MilesA Posted January 14, 2020 Report Share Posted January 14, 2020 Thanks Tom - that's better! Got it off eBay some years ago. About £10 from recollection. Miles Quote Link to post Share on other sites

Nigel C Posted January 14, 2020 Report Share Posted January 14, 2020 so do I take it that the red end cap is like a button that you can reset? And thinking that this would be positioned to forward direction? Quote Link to post Share on other sites
Chilliman Posted January 14, 2020 Report Share Posted January 14, 2020 Just a ball bearing sat in a cup that completes the connection & gets knocked out with an impact, just press the red top cover to reset, as far as I'm aware it's orientaion in terms of front/back would make no difference to how it works....

john.r.davies Posted January 14, 2020 Report Share Posted January 14, 2020 Me too. There is a second version with three wires, that will light a lamp on the dash to tell you thatit has triggered. Useful if the "engine failure" you have just suffered is only due to mounting a kerb. Won't happen parking but might at speed! JOhn Quote Link to post Share on other sites
MilesA Posted January 15, 2020 Report Share Posted January 15, 2020 Yes John, the version I have has the third connection between the two wires shown in the photo to wire a lamp. Before I installed mine I did some research (because I am not very good with electrickery) which suggested that the two wires were specifically positive and negative. From recollection there was nothing so simply as + or - stamped next to each wire but a letter code. May be relevant if you get one of these. Miles Quote Link to post Share on other sites
john.r.davies Posted January 15, 2020 Report Share Posted January 15, 2020 (edited) I can't recall how mine is wired. I worked out which was which on the bench, with a couple of lamps, knocking it against the bench until one went out and the other lit. If anyone wants, I can go and write it down! If you get one, if at all possible get the connector to the loom as well, with the wires cut off long. The pins in the switch are not ordinary spade connectors, and it's much easier to wire it in this way. JOhn Edited January 15, 2020 by john.r.davies Quote Link to post Share on other sites
Charlie D Posted January 15, 2020 Report Share Posted January 15, 2020 A friend of mine recently got a tracker for his car ( a very common low cost item - model TK103). Apart from using it to locate the car it has many other functions available, one being an “SOS button”. The 3 wire inertia switch would be an ideal “Sensor” to replace the button. What happens is that if the inertia switch is activated a text message is sent to a mobile phone (as specified by the user) with the message “Help Me !” and a link to google maps with the location of the car. Possibly a life saver if you end up in a ditch on a remote country road. The message is repeated every 3 mins. until the driver resets the tracker. Charlie. Quote Link to post Share on other sites
pinky Posted January 15, 2020 Report Share Posted January 15, 2020 Would these later inertia switches be seen as an upgrade to the standard tr6 standard inertia switch. Pink Quote Link to post Share on other sites
john.r.davies Posted January 15, 2020 Report Share Posted January 15, 2020 Would you use other fifty year old safety kit? J. Quote Link to post Share on other sites
michaeldavis39 Posted January 15, 2020 Report Share Posted January 15, 2020 I would definitely trust my life with a new switch - value myself more than having a switch that looks original as surely most folks on here would. I've heard that the old switches weren't that good anyway rusting up inside and sticking apparently - so my classic mechanic tells me. Michael Quote Link to post Share on other sites
Spit_2.5PI Posted January 16, 2020 Report Share Posted January 16, 2020 Keep the old switch in its standard position (but not connected, just dummy wires) for looks/originality and install the new switch & relay hidden away somewhere. Cheers, Richard Quote Link to post Share on other sites
pinky Posted January 16, 2020 Report Share Posted January 16, 2020 Thank you gentleman I will sling the original and fit a new one I'm not into originality Cheers pink Quote Link to post Share on other sites
