Banana jacks, that is. Hard to believe, but, even in this day of supersmall connectors and RF interconnections, basic test, medical, and industrial applications still use the venerable banana-style jack and mating plug pair.
Safety banana jacks from Cal Test Electronics are available in threaded-body/panel-nut as well as push-in-body styles with a choice of eight wire-attachment methods and 10 colors (Picture).
