Equipment leads

[ppppenguin]

Looking through my drawer of 4mm plugs, most have some kind of sprung section that can be eased outwards to give a better fit in loose sockets. Some others have splits in the pin so the pin can be expanded. Not sure I'd like to use any of them to make a lead where I'm probing high voltages. Some are awful in this respect, with metal parts easy to touch. The old fashioned stackable type with a cross hole are probably the worst. Others aren't too bad but I'd need to be careful.
