I can see 4mm plug leads might get left connected somewhere and the live ends touch on the bench. But 4mm plug leads are mostly not shrouded. I only have shrouds on DVM cables .. with handheld points on the other end. So an accident requires that I unplug the leads from the meter, leave the unplugged ends lying around, and then probe some high-energy circuit with the disconnected probes. The only time I unplug DVM probes is to swap them over to the current socket. There's no reason to leave them unplugged. The vanishingly small chance of that happening and not some other fatal error is easly beaten by all the inconvenience of them, such as the lack of stacking, the incompatibility with unshrouded sockets etc. etc. Absurd. --- End quote --- The only absurd thing is how nearly every single assumption you’ve made is wrong. As others have shown, safety banana leads are available and quite common, including stacking ones. I like using them wherever possible because they can’t short out on anything. A couple of adapters handle compatibility with devices that don’t accept them. You can even get stacking plugs with retractable sheaths that plug into everything but are sheathed when possible. There also exist binding posts that accept safety banana plugs, giving total flexibility on e.g. bench power supplies. (I’d love to see these displace ordinary banana binding posts altogether.) |

That kind of design is in my opinion the best of both worlds. I'm with Tooki on this one. Or the type that is shrouded but doesn't have binding posts. If you need a way to connect a wire there are adapters for such - https://fr.farnell.com/en-FR/staubli/22-3007-22/plug-safety-clip-on-red/dp/1085557 https://uk.farnell.com/schutzinger/sdk-799-rt/safety-quick-release-terminal/dp/3224560 |

Then if it turns out to be something I use a lot, I’ll make a soldered version. |
