What is length of pop out switch

[cradlescyth]

My 1930 A was giving me fits starting and running. Due to knowledge acquired hear on the BARN i found the pop out switch to be bad.
Took it out and tested it - bad.

Acuired a N O S switch and installed it. It was at this pont i felt the
switch assy was a little short in length. Thus the question " Are all pop out switch assy the same length?"

I seem to have read that they come in two types. Sold back and removable back, the latter is the one I installed. It was real tight installing
it.

My eng. # is June 1930 and is registered as such. I would appreciate any info possible.

Thanks

It depends if you have the oval or round speedometer, I think the round
takes the longer cable.

28-29 pop out cables are shorter than the 30-31 the pop out switch is a little different from oval to round speedo.

I have an early 30 PO switch fully restored to show show quality. Still in box. I was told that the early 30 is different from the later 30's. I have the oval speedometer. My car is a Feb 30.

Thanks everone for comments. My spedo is round, but this in its self does not definatively determin the length of the cable. I think the one I installed is shorter if two lengths are made. hopefully will find out if it works today.

I measured my round speedometer ignition switch cable and it is 29 1/4"
from the end of the threads to where it enters the switch.

Yes, as mentioned the round speedometer will use the longer cable with the popout with the removable rear cover. I'm not home, so I can't measure one right now.

Notice how the cable for this aftermarket ignition is pushed way over to the side on my engine head. This is because it's made to fit the longer one for the later A's.

Thanks again guys. From the looks of your Picture Tom I have the right one.

[Tom Wesenberg]

Thanks Vince. I was thinking that's how it was, the later style (1930-1) cowl is the determining factor for the length of the cable.

Now, one more question to be sure on the switches, are ALL the non-removable rear cover switches the short cable, and are ALL removable rear steel cover switches the long cable?

[Tom Wesenberg]

Here are a couple pictures showing the lengths of 3 of my original cables. The top cable is the 1928 with the forged mounting lug. The middle cable is the 1929 with the steel separate bracket. The bottom one is the longest and fits the round speedometer.
They are 28 1/2", 29 1/2", and 30 1/2" to the end of the metal sleeve.
