Folks,

I found a switch this weekend at a local swap meet that I was certain is the early TR250 hazard switch, but now I think it's not what I need.

Since it's gonna be a while before I take apart the dash, can anyone confirm if the switch I've purchased is in fact incorrect, if it could be substituted for the original one, or if this newly acquired one could be disassembled and the pieces used to repair the on presently in my dash?

Here is the one I bought:

Here is the remains of my previous hazard switch presently in my dash:

Here is what I think is the hazard relay in my engine bay:

Here are pages from the Bentley manual.

It would seem I have the "earlier" 4-contact switch in the dash and the relay in my engine bay. It would seem this newly acquired switch is the "later" 6-contact switch containing the hazard circuit.

Thanks, as always......

That switch was only used one year (1972). Earlier switches had a flat rocker and four contacts, not curved like the one you are showing. Later (1973- 1976) looked like this:

Not sure if you can use some of the parts from your purchase to repair yours.

But, assuming Joe is correct about it being a 72 hazard switch, and the diagrams in the Dan Masters book are correct; it should work as a substitute for the original switch. Connect the two LGN wires to terminals 7 & 8; purple to terminal 4 and purple/brown to terminal 5. Terminals 1 & 2 can be left disconnected.

Physical mounting might be an issue, though. I vaguely recall reading that the early switch is just a tiny bit narrower than the later, meaning you'd have to open up the hole in the dash to mount it.

There are two listings on e-bay for new hazard switches, both listed for Tr250, 69 thru 72.
Randall has taken the extra step to do the research for the wiring, Thank you sir. That will
help a lot of folks looking to replace a switch. As Randall points out, and listings state that some filing has to be done
to make the new switch fit.

Crud..... I should have known it was too good to be true. And while it was a good deal against the $189 switch sold by Moss (which isn't with a white symbol at that) this switch wasn't cheap.... Are these worth something? Just me, but I would rather sell this one and keep looking for the original than mount a curved rocker where a flat one is appropriate, especially if it means routing out the dash to accommodate it..... sad smiley

Any suggestions on finding an original one of these?

Thanks, all....

......and can someone confirm whether the hazard symbol should be white or red on the TR250? It's red on the repro available 148401 hazard switch....

Andrew....do I have a deal for you! I actually have a casing for an original 250 switch.....actually 2, but don't have the guts. I managed to find another complete one for my 250. Yours looks like all the guts are there, but no cover. I'll let one of mine go. If interested, PM me.

We are working on the 65th TR250 built. Here is a picture of how the switch and dash looked at the beginning of the project. As you can see the symbol is white, but it is near the upper end of the switch rather than in the center.

The dash looks much nicer now but we re-used the switch without restoring it cosmetically. We are hoping it will still work

"As you can see"? I know my eyes are starting to go but isn't the hazard switch hidden behind the steering wheel in that pic?

In my last post I pictured the wrong switch. Here is a picture of the dashboard in the car we are working on now. It shows the Hazard switch. As you can see it looks the same as the switch Andrew M asked about..

That's exactly what my switch is on my 250. Has four terminals on the back. Rare as hens teeth.

Andrew,

You can make that switch work if you can make it fit. The original switch has four terminals - when 3-4 are off that means power is going between those two terminals. When the hazards are on - that means power is going between terminals 1-2

If you look at the new switch, in the off position power is going between 8-7 terminals. In the hazard position power is going between 3-1-2-4 terminals.

You can check this out with an ohm meter to be certain.

So if your original switch had the 4 terminals then you can replace it with the other switch which will do the same thing. No need to change anything else.

Regards

I think you will find the 6 prong switch also has small male fittings.
So it will be necessary to make up some pigtails of about 3 inches so you don't have to cut your original wires. Hoping to find the original switch one day. Only problem is, you have cut the hole bigger.
Be there done that on the '70 TR6.

Folks,

Installing my hazard switch. Quick question......

I'm assuming the arrow should point "up" and you should press the switch "down" to activate the hazards. I am basing this off of the "Official Owners Handbook" reprinted in my Bentley Manual (pics below), but the pic seems to be for an early TR6 and the handbook covers the 6cyl TR range. Plus I've seen 250's every which way including some fairly "concours" vehicles.

I can configure the switch to do anything, but I want it to be original. Do we know for certain the correct orientation and operation of the original switch on a TR250?

Andrew
