DICKY JUMPER WIRES

Good morning all,
Has anyone used these jumper wires form JAYCAR.

Plus others that they stock.

I have, and I found that the plug / socket breaks off quite often.
Two pieces this morning.

You may not know why until you realize that the wires inside are 7 strands of 0.09mm copper coated steel
Crimping to the plastic sheath of the wire is not very good so a lot of strain is applied to the thin steel wires.

If I had a choice I would avoid them but there is no guarantee that buying them on line will have any better results

That's my rant.
a good bit shorter than Daves.

Thank you for listening.

BILL.

Indeed these are thin, they're only designed for signal levels (eg less then a few hundred mA).  When I need thicker ones I crimp them up myself.

Rule of thumb: never expect there to be copper in anything unless you can cut it open before buying it.

Ya, most are junk nowadays, add these crappy jump wires to sub par breadboards that are everywhere and it is surprising one can get a breadboard project to work properly. Scratched my head for days trying to get a Jupiter receiver to work properly on a breadboard. Probed around and the supply line was dropping to 4.2 volts on the breadboard. The jumper wires and the breadboard could barely pass 100ma. Was thinking of dropping some dollars on a quality 3M breadboard. Interesting on the SparkFun jumpers, will have a look.

If you buy enough of these cheap jumper wires, you'll get one that is open circuit from the box. Of course no one expects that when breadboarding a circuit, so fun and games ensure.
