Different door jamb switch sizes?

[rescuediver1982]

I took the door jamb switches out of my 73 satellite sebring plus (now roadrunner clone) for painting. One was broken and didn't spring back anyway. However, I have lost them! I have ordered 2 sets that said they were for my year/model but they are way to small. The factory threaded hole is maybe 1/2"? vs the 3/8"? these are... does anyone know what size these are or have part numbers/sources for replacements?

Just went through this with my 71 R/T. one side was a 2 prong and the other side was a 3 prong switch, measure your diameter. Many sources on the net. I found a hard to find one at jimsautoparts.com

since 72 all become 2 prongs. 71 is a one year setup

I remove my 74 door jam switches with 9/16 hex wrench as far I recall, so... I guess this mean my car is 1/2" thread hole ? I know several changes were made by Mopar by those years, soooo this can be confusing and just need to try to match your assembly

On a 73 the door switch should have 2 terminals on left, one on right. Parts numbers are as follows:
3488875 right side/passenger
2947844 left/driver
both should have the same size hole.

They won't work unless you cut and redo the connector

No one makes the larger door switches 1/4 pipe tap. You can however get them with the smaller 1/8 pipe tap. What I did was use a pipe reducer 1/4 outside and 1/8 inside. I cut off the 1/4 threads and was left with a hex head with 1/8 pipe threads inside. I drilled out the door jam switch hole so that the reducer would fit inside and welded it in. Now you can use the smaller door jam switches.

I just checked at Megapartsusa.com and now they have the 1/4 NPT door jam switch

Thank you! I was trying not to use a reducer but it has crossed my mind! I actually had just found them in mega part’s Site and ordered them. I also got a new connector to Rewire my headlight harness. Their prices seem really good!

I ran into the same issue with my 73. To top that left and right are different as pictured above.
Passenger is 1 terminal 3488875, driver 2 terminal 2947844.
In the end I bought a used one, works fine.

I have these if you're wanting OEM. Looks like I have 2 large diameter ones, both with single connectors. One double connector with small diameter and 3 single connectors with small diameter and sheaths over them.

Lane at Vans Auto just sold me 2 door jams for $20.-- These were single pole, large thread. Listed as a 71-74 part https://vansauto.com/product/door-jamb-switches-71-74-b-body/

They will fit and could work for passenger side ( diff terminal thought at least on mine ), but drivers needs at least two prongs as minimun to be able to get the warning buzzers working just with driver side door. Using single terminal on driver side and splicing blacks and yellows together will make the warning buzzers work with passenger side too.
