Jumpers?
July 22, 2007
Do any of you know where I can find 8-contact jumpers / shunts (RoHS compliant, please) for sale?
I have a block of pins with 4 jumpers on it, and they all need to be either to one side or another, and I would rather not have four separate jumpers which need to be moved.
To clarify, here’s some crappy ASCII art explaining it:
The pins:
***
***
***
***Will have jumpers / shunts in place like this:
XX*
XX*
XX*
XX*Or this:
*XX
*XX
*XX
*XX
I can’t find them for sale, though. They must be a somewhat special order item, I guess…
Then again, I can’t remember the last time I saw jumpers like that on a commercial PCB, either.
what are you talking about? they are a lot of things with those shunts on them.

but i doubt you will find anyone who will label or test them for ROHS.
Those are 2 place, and I have no problem finding those RoHS compliant. What I want is 8 place… Basically, four of those stuck side by side.
Worst case, I guess you could glue two jumpers together and wire the jumpers together where they meet from the top…
err, four, I mean, and wire those together (now that I’ve read your ascii art correctly).
Actually, they just need to connect left to right… Perhaps I should say the variants can look like this:
Plain pins:
* * *
* * *
* * *
* * *
Position 1:
X-X *
X-X *
X-X *
X-X *
Position 2:
* X-X
* X-X
* X-X
* X-X
Oh, in that case break out the glue, it’ll be just a few second’s work for each unit.
It’s probably not even worth it… They will be set once, at installation, and most likely left for years.
I was just hoping I could find them pre-made, because it’d just add more polish to the finished device.
What would be even better is sealed DPST DIP switches, but I can’t find those (even unsealed) anywhere. I found some SMT ones, but they weren’t RoHS, and were SMT.
