that seems to be a normal SPDT single pole dual throw switch.

from the data sheet I would think it wouldn't suit your purpose since it's 4mm wide.

🤔

Any suggestion for something that would?

Well, you could design small PCB with 2.54mm female connector on back side which sits on jumper row. Then a normal th DIP-switch on top side. Long enough so that you can cut it to size you need. Maybe it should be asymmetric then you can rotate it if needed. Just a thought.

since dipswitches tend to be only off or on, your suggestion would not work for those times that a jumper specfies either 1-2 or 2-3.
edit : spdt dipswitches do exist, yet the ones i'm looking at have a different footprint than a neat in line 1 2 3 pad print.

Shame noone has made a switch that just plugs into jumper pins… 🤣 (a super compact one I mean) obviously I know front panel switches exist but that would be a rats nest
You know what, this gives me an idea..

We need a rear I/O bracket that has a bunch of DPDT switches on it like 20 all in a row that we could run to the jumpers on the motherboard. (It would be a rats nest but we could overclock and change settings without even popping open the case to chase jumpers

this seems very close

Second one looks great!

Thin enough to go side by side?

Where do I order in usa?

Closest I've found is https://www.farnell.com/datasheets/530177.pdf
But the third row is 2.54mm too far apart. Could trim those legs off to make at least a SPST set that would fit. Assuming the switch body doesn't clash with any motherboard components.

Problem looking for parts is that DIP switches are sized to fit in a DIP chip outline, so distance from one side to the other is 0.3" / 7.62mm.

Last one looks nice.

These also need a no connection position as well in some applications.🤔 but these would work for many of the jumpers I would use it for

For sure that is true in some applications. For what I've seen clock gen select pins are usually internally pulled low/high. In this case it's another position basically for storage. That's how it's done in P5A.
Voltage controller select pins behave the same way. Input is either OPEN or tied to GND/Vcc. As a summarum (two pin) SPST DIP-switch should work in P5A if connected to correct pair-of-pin rows. I don't see problem in SPDT DIP-switches either, should be a job easy enough if you really need it.

I would not connect any voltage/frequency select pins to backplane via long leads. It may work, but EMI inside coputer chassis can give interesing results.

Indeed 😀

Kinda pricy but so worth it! Spent like 15 min chasing jumpers all over my computer yesterday alone 🤣. Pick em up and they fall use tweasers and they shoot out at the speed of sound. Lol

Now I just gotta figure out which jumpers are okay being 1-2 or 2-3 and not open

Found these on a google search for “jumper switch”

I've done this!!!

That was my solution! Just use hookup wire with some switches and route them to the front where I don't have to even open the case. In fact that case has a special party trick where it opens like a giant clam, giving you SUPER easy access to the CPU area. I used this chassis many years ago when I got a 100-pound pile of CPUs that needed testing. Made everything easy peasy.

That chassis has an Asus P5A in it, btw. And if i'm not mistaken, I need to get that system out and take some pictures of the board as it has sound and 1mb L2. I forget who wanted the pics, but i'll eventually get to it.

In my opinion. The best way would be to make a small PCB. have it fit on the jumpers. And put big lever dip switches on it like these: https://www.digikey.com/en/products/detail/gr … 6STC04T/2680741

side note - Why are those lever style dip switches so damn rare? I mean, I have them on some trainer boards, but nowhere else?

I wouldn't try to replace jumpers with dips. I would just connect a remote switch to them.

I was thinking of using a keyed switch labeled "Turbo" for the front side bus jumper connection in my next build. I don't think the board would like it be switched while on otherwise I would go for a classic turbo switch.

Yeah maybe a back panels insert would be cool with toggles. And just plugs onto the jumpers.
