turnsignal switch differences

Recommended Posts

  I have a '47 Windsor that needs a "new" turnsignal switch assembly. Is the whole family the same when it comes to the turnsignal switch? And doe's that go for '49 First Series?  IN my area these older cars are nonexistent.  Thanks for your help.

What do you mean by "whole family"? PDDC ? for 1947

The Chrysler turn signals are factory, they are not with Plym and Dodge, those cars, usally got aftermarket Signal Stats as a dealer add on.

Are you stating you need to source a new signal switch? If so look on Epay, and check out this add out, is this what you need?

The factory type, work with the tail lights, but do not have the brake lights working with them.

The stop lamp on the trunk is the only brake light, now if you want the tail lights to also work as brake lights, signals and running lights, you have 2 choices.

1) you wire in a couple of relays to make this all work as a unit, or

2) you use a 7 wire aftermarket signal switch, like a  "Signal Stat 900", which is 7 wire set-up style, those work the best and allow all the tail light to work as a complete unit with signal,brakes and tail lights, while also having the trunk mounted stop lamp working with the brake light circuit, but not interfered with when you use your turn signals.

Clear as mud???.....Good Luck

That Chrysler Desoto unit will fit on a dodge or a plymouth. You are right not many plymouths got fitted with signals but I have seen a few. The unobtanium part is the high beam/indicator light for the plymouth.

 

I second the use of a signal stat 900. Available in black or chrome and they work on 6 12 or 24 volt just by changing the bulb.

All 1941-48 factory installed MoPar turn signal switches for the cars are all the same except for the exterior plastic housing colors and type of plastic.

      I was hoping that the assembly for a '49 dodge would be the same as my '47 Windsor. There are two listed on E bay that look the same as mine. I KNOW, I've a garage full of    things that I thought might work , but these things are just too expensive to take a chance . ( $89.00 and $125.00) . The part #s are different BUT it's listed as '49 instead of 1947. Thanks for help people.

Looks like 49 dodge is the same too!

Make sure the springs are there as in the pic as if not the switch will not operate correctly!

        Well, I think it will work . The springs are a different weight than mine but, if it presents a problem I can just exchange them with the ones off of mine. They are only one coil off by my count, and that might be the operator, (ME) . They have the same Canadian patent number 1943 on the top between the lever pivot and the 2 wheels that return the lever to neutral.      SO are you willing to sell the one you are showing me , no pressure their are 2 on ebay for another day +/-. Thank You for your  time and effort. I really appreciate it. :D

    That's OK , I just want thank everyone for helping me.  Without you I'd be waving my arm out the window. What % of people would know what you were doing anyway.

Half would think you were upset at them, the other half would think you were extremely friendly, some might even wave back.

Most importantly when making turning gestures with the arm out the window is don't make a single finger jester as in pointing with a single finger. And don't do the "live long and prosper"  jester as that can also be misconstrued. Keep all 4 fingers side by side otherwise I guarantee you will piss someone off. Voice of experience has spoken.

I was using my arm to signal while driving my model a before I installed the turnsignals, a young girl in the approaching lane saw my signal for a left turn and flipped me off. Guess the under 70 crowd has no idea how hand signals are suppose to work. But I'll get over it as soon as I stop laughing. :eek:  :D

I was just having this conversation with someone and I noticed this post.  I have a 42 Dodge with factory original turn signals that I had to find a housing for a long time ago. I have since bought a bunch of Mopar Books that explain the shared pieces and the slight differences.  I just picked up a 49 switch and although they appear very similar, there is an ever so slight difference.

 

In my 1942 Dodge parts book it lists under section 8U a Direstional Signal Switch.  The switch mechanism assembly is part number 977749 and part number 908793 for right hand drive.  The chrome lever is 932135.  The chrome lever with the integral straw yellow knob is 983991 and the straw yellow knob is 981415.  The housing is 981507.  There was no mention of color for the housing.  

 

My 35-42 Dodge parts book shows directional signals were offered in 1941.  Switch mechanism was 939567.  Housing was 932136 up to serial number 30390499  then it was 935526 except for the 2 door coupe and 2 door sedan which had 934557.  The canceling ring is called a trip finger which is 866923 for 41 and 42..  They are showing lever number 983991 for both 41 and 42.  The knob is 903830 for 1941 and 981415 for 1942

 

My 42 Desoto Book shows Desoto used the same switch mechanism as the 42 Dodge.  Chrome lever was 932135 like the 42 Dodge.  It had an ivory knob 973151.  Integral ivory knob and lever were 983992. Housing was 981508 so there may haver been a slight color difference from Dodge.  The release finger was 866923, same as Dodge.

 

My 42 Chrysler book shows Chrysler used the same switch mechanism as the 42 Dodge and Desoto.  Chrome lever was 932132 and used on the c34 and c36..  They also list a number 941771 for black front compartments (ex limo.) model c37.  Limo c37 would get 947014.  A mottled lever 983993 was available for all models.  42 Chrysler had a knob 981510 for the c34 and c36  and 947008 for c37. Housing was 981509 so there may haver been a slight color difference from Dodge and Desoto.  The release finger was 866923, same as 42 Dodge and Desoto.

 

My 42 Plymouth book shows Plymouth used the same switch mechanism.  Chrome lever was 932135 like Dodge.  It had an beige grey knob 903831.  Integral biege grey knob and lever were 983990. Housing was 981506 so there may haver been a slight color difference from Dodge, Desoto, and Chrysler.  The release finger was 866923, same as the others.

 

The 49 one I recieved says DONA on the back so I don't know if that is an after market.  I don't remember seeing that on the 42 one on my car.  I've also seen a variation with ODONA on the back.

 

Attached is the 49 DONA switch next to a 42-48 housing.

 

 

The 1946-48 parts book shows under section 8-50-80 a Directional Signal Switch.  The switch mechanism assembly is now part number 1163990 and part number 1232776 for right hand drive, less the base.  The chrome lever is now 1154240.  The beige knob is 1161480.  The black knob is 1157956.  The housing is 1154203 and is now prime for paint.   RHD is number 932138.

 

My 1954 Pats book shows under section 8-50-80 and on, the turn signal switch mechanism 977749 being used for 1942 - 1948 Dodge Plymouth Desoto and Chrysler so that must equal 1163990.  1949 Dodge plymouth used switch mechanism 1257511 and Desoto & Chrysler used 1235606.  The directional signal housing is listed as 1240994 for 1941-42 Plymouth, 41-48 Dodge, Desoto and Chrysler.  Nothing shown in this for 46-48 Plymouth however I think they shared through 48. All DPCD 41-48 share the same cancelling finger.  They show the same chrome lever for 41-49 Plymouth as 41-49 Dodge, 41-48 Desoto, and 41-48 Chrysler however I think Chrysler was different at least in 42.  For knobs 1942 Plymouth and 46-48 Chrysler Eight show 983990. Knobs for 46-49 Plymouth and Dodge and 1946-48 Desoto and Chrysler show knob 1161479.  This may have been a generic color option by 54 as this is not what the parts books said in 42

        WOW ! !  talk about information overload, I'm making a copy of that.  Thanks for all time and information Ron.  I've purchased a NOS  '49 Plymouth switch hoping it a first series but I don't think it is, it's bigger. The switch is the same dimensions for my '47 Windsor and the  '49 Plymouth  BUT the steering column mounting end of the bracket is 2 1/2 inches on the Plymouth and only 2.25 on the Windsor.

       

       So  I am going to mount the '49s switch mechanism on the '47s switch plate and see how that works.

 

 

Ron,  You are a professional typist aren't you.    Thanks again.

I'm pretty slow with 2 fingers.  

 

I did some more side by side comparisons.  

 

The round hole in the plastic housign that sleeves over the steering column is 2 1/2" at the surface and tapers in to 2 3/8".  The 42-48 style  a 2 5/16" hole with a slight lip up and the hole tapers to 2 3/16".  

 

The gear shift side is different too (see attached)The beveled recess is almost the full depth of the housing on the 42-48 where the 49 stops about 7/16" down from the top face.
