CableWholesale Jumper Connector 2.54 mm for 3 1/2 Hard Disk, 100 Per Bag (30J1-00100)

I haven't needed jumpers in a looong time... I struggled to get the first one on, and then the rest were impossible! Then when I flipped it around, it slid right on. D'oh! The little line is on top!Great buy in bulk. Wish it came in a ziplock, but I have plenty of those around. I am using these as a switch on an electronics project with "Gino 10 Pcs 2x40 Pin 2.54mm Pitch Double Row PCB Pin Headers".

I am using these for custom PCBs. They are cheaper than Digikey options and work as you would expect for 0.100 headers.

Strange how you can never find one of these when you want one. This 100 pack solved that issue (for a while, I'm sure). I've used about 10 of them and none have had any issues so far. I counted them and there were actually 100 in my pack... so that's good. I rated four stars, because there's nothing that really stands out - they're jumpers after all.

Didn't think I would be commenting on these. However, the last pins I used had a smooth, block top.The pliers would slip off when I would remove them. These jumpers have an exposed wire on top,making them much easier to remove. Also, great price! Will I use all of them? Probably not.However, I will always have a spare for a family member or friend. Brownie points for me!

I'll probably never actually need this many jumpers myself, but I have friends bum them off me sometimes, and/or sometimes lose them myself. Now instead of driving myself nuts looking for them, or checking the vacuum cleaner bag... I know I have plenty more where that came from.

I recently needed a couple, couldn't find any, so I order this set.Now I have a lot. (I haven't counted, but there are supposed to be 100). I spot checked a few, and they all look just fine. I used a couple, and they worked.Hopefully, next time I need a jumper, I'll remember where I put the rest.

They're Jumpers! They work! They look like pin jumpers. Not high quality machined parts or anything, but was that really what you wanted?

Package of 100 high quality jumpers. One end has a ridge to make it easy to remove with your fingernails. The fit snug on standard pins and would be difficult to misalign.
