That was my situation Randy, my old original switch is still working but the two plastic tabs that hold the switch in the dash are broken so the whole switch wanted to pop out of the dash. Probably due to 50 years of being in the sun. Therefore my quest to create a new one started. Moss has the switch (red only) but I thought it is a bit on the high cost side (my personal opinion). I'm trying to make a few that will pass the "eyeball" test and do a limited run of them for the few enthusiasts that need them. If your top rocker cover is still nice, the overlay really looks as good as my picture shows. Does your 70 TR6 have the 4 terminal switch, once again I thought only 69 TR6 had these. My 70 GT6 has the later 6 terminal switches that are still available.

This switch in the TR250 is miserable to get at.

Brian-

I am not sure what commission number the change was made, but Moss lists that pricey switch for cars through 1971. My 70 has the 4 prong setup, and yes its still a pain to get at.

Hi all. I think I'm going to call this last revision the end of this project. I think ii's an acceptable switch that will look and function good in my TR250. It was a bit of a process, not so much on 3D printing the rocker switch itself but getting the "triangle" looking good. I think I've got it now. Is it perfect--no- but looks better than the old one I had. One observation might be that for a 50 yr. old car the switch now looks TOO new but exposure to sun and weather should give it some age. In picture -1, my original old switch cover is there but with a new "face". The lighting isn't good in the pictures, too much light reflection but you get the idea. Now I have to pop this in my dash and you all know how much fun that will be. My TR is in its winter garage now but when the weather gets better, I'll go at it. Took me 8 try's to get it to this point but I think it will be a good addition to my TR as I clean up the details. Now if I could get good enough weather to repaint the TR, it now needs that after 20 years. Now onto my next project.

Great work Brian.
Our 250 is fairly early.......460. Known since about '77, Believed to be the original switch. Hard to tell the original color of the arrow as the arrow seems to have no color left. Faded is the word for the body though. It is a pale pale grey compared to any of the pictures and is a 4 terminal switch. As far as the original color of this switch, it is too hard to tell. One would guess that the 250 being the "safety" year that red might have been the color of the arrow, but who knows as white is the color of the "pictures" on all the other switches. Either way, if you have any spares left, we would be interested in one.

Thanks.

Brian and Bob, I have TR 250 CD 7034 and my original switch was white but the replacement I got is red. Found another switch at car show in Penn last spring. Paid $75 but wanted to have one as back up and it is red also. I would also be interested in your 3D copy.

Brian,
Great looking switches. I posted my first comment before I looked at end of list. You did a super job.

Thanks Ed, Chris and others. I have a list running of those that are interested. I'll soon define my plans to make a few available. I hope you all will find my "distribution" ;method interesting. Basically you'll end up with a new switch in the $55.00 range. Red or white triangle.

Also something to think about for those TR250 owners that have purchased a TR6 switch but found the switch is wider and you had to carve out the dash in order to fit it in the hole. I got a suggestion from another member of this forum for this. Even though the rocker is wider on the TR6 switch, it still goes onto the switch body the same. I'm going to make a switch cover that will be the same width as the TR6 switch but will have the flat rocker instead of the arched rocker and will have the triangle the color of your choice. That way you will have the "looks" of a 250 switch but it would be on the TR6 body. In other words, you will be disguising the TR6 switch to look like a 250 flat rocker switch. Anyone else interested in this approach?

Sounds like an economical approach, are the "guts" of the two switches the same?

No Drew, the TR6 switch "guts" are not the same as a TR250 switch BUT, how the rocker cover operates on the internal parts IS identical. I can take my new TR250 switch cover and put it on a TR6 switch body and it works fine. My point is, a few TR250 owners purchased TR6 rocker switches because for a long time the TR250 switch wasn't available. To install the TR6 hazard switch in the TR250, you have to make the opening in the wood dash larger to accommodate the wider TR6 switch and redo the wiring. For the "purists" it doesn't look quite right since the TR6 rocker has an "arched" switch cover. You could use one of my new TR250 covers and put it on the TR6 switch but now it looks weird with the smaller rocker cover sitting in a hole in the dash that is much larger. For those that just want to make the switch "look" more normal, I was going to make a new rocker cover that is the right size to fit the hole, make it flat like the TR250 but it fits on the TR6 switch body. Might fool a few people at the shows because most look to see if the flat rocker is there. Just my thoughts. I've got it designed, just have to print the part and process it. Right now I'm having printer problems but I'll get it. These printers are "finicky"

hello, I too am the owner of a TR250 in need of this switch. On mine, it was broken but I managed to cobble a fix and it is working however I too would be interested in buying one of yours. Please add me to your list of possible customers...

I am quite impressed with the work you are doing... Good job!!!

Regards,

Arched switch cover? Are we talking about the 72 switch? The 69-71 switch cover is the same as 250 as far as being flat. I’ve not measured them, but I believe both are 4-prong.

Good question Todd. I actually don't know for sure, I had thought the 4 prong-flat switch stopped on the early 70 TR6's but maybe it was carried over to the 71's ???? Learn something every day.

It's me again Steven Archuleta and I wanted to thank you for responding to my post. You asked what color I am interested in. I just checked mine and it is so old it does not have any color left on it so I guess for me it really dos not matter that much. Red or White,, either will me fine.

Again thank you

Ok Steven, I'll flip a coin. ----------it came up WHITE !!!!!

I'll be posting how to purchase these and other items in the near future. I'm building a small web page to facilitate this.

Here is the rendered model of a modified (width) flat switch for those that ended up in the past, buying an "arched" TR6 switch for their TR250. This flat cover will snap on to the TR6 switch body. This will then be the look of a TR250 flat hazard switch in your dash for those that made the hole in the wood dash larger, might fool a few purists at glance
