Electrical test connectors.

Finally found some time.
Cost was about £4
I’ll make some slimmer ones next week.

@Chris1234 Is that your gnarly metal workbench or the advertising picture?
They look useful - where did you find at £4?

It’s the bench at work!

I made them, magnets with wires attached soldered onto silicon wire then pushed into female 4mm banana connectors.
Very simple!

Diameter is around 6.3mm.
I’ll make some slimmer ones soon that should be around 5.2mm using acetal rod rather than pushing the magnets into banana plugs!

So glad I read this thread never knew I needed a set of these

I wonder if maybe an apprentice could hold the probe on for you?
Doh! Of course not...I'm getting worse!
I do love magnets though...and by coincidence, two days ago, during renovation of an old building, I dropped my favourite Bahco wrench down the wall cavity (I was installing a 22mm radial circuit at the time, in the attic...water, I hasten to add, a water supply!). With a powerful torch I could just glimpse it lying there, 10' down, in the dust. I got a length of Terylene cord and tied on a magnet I got out of an old hard-drive...and fished it up first go! Hurrah! I say it was my fave wrench, it is actually a replacement for one I bought a few years ago, but that one went missing when a plumber was installing a new boiler in my garage and I was assisting...
just saying...
Anyway, those magnets from hard-drives are brilliant, if you can be bothered dismantling them. (Sad, eh?)

Every day for the last year I’ve been thinking I need some test probes for my multimeter that have a small magnet in the end to connect to the screws on contactors, MCB’s etc.

I found these on eBay, but the diameter is 7.5mm so a bit big for some connection screw holes.

Has anyone seen any anywhere else?

Thanks.

Can’t see any magnetised probes in the link?

The links are for the parts to make the probes

Indeed. I have a collection of them stuck to the side of my filing cabinet. One lives in the van for finding joists and studs (by attraction to the screws or nails).
