66 K-10 back up light switch
 

Does anyone have a photo of the correct back up light switch for a 66 K-10 4 speed transmission. Is there someone that offers the correct back up switch for the 4 speed transmission. It appears I have everything but the switch. Thanks in advance.

here is a pic of backup light stuff, for 4 speed transmission. i dont know if C-10 is different then K-10.
i dont know of anyone who sells the switch, one post i read suggested trying to find a barrel switch with a push button from an electronic supplier.

Thanks for the info. Great stuff. Any chance I can bother you for the length of the switch. Like length overall, length of main body, and then the length of the moving up and down part of the switch. This will help me find the correct switch. It appears I have all the other items intact on the transmission. Thanks Again, I hope you and your family have a great holiday.

hope this helps.
the button doesn't click, its spring loaded and extends when the lever isn't pressing it.
the button will press in as far as the threaded collar.

If you can find a top cover from a 1967 sm420 it has a factory built in reverse contact switch. Much better and very much so less problematic. All else being the same.

Thanks again for responding with great info. This will help in a big way. Happy Holidays to all.

Can you post the part number on that top cover? Can't quite make it out in the pic...

Thanks!

There's a thread in these forums where a member found a newer switch that works.
I'll see if I can find it.

Thanks Lost my 65. Huge help. I am a little surprised to see they are hard to come by. Happy Holiday's to all. Once again you guys rock. Now all I have to do is find a good used on, or NOS one. The search begins.
