A clip is a simple mechanical device for creating a temporary electrical connection, and is named for its resemblance to an alligator’ s or crocodile’s jaws.Functioning much like a spring-loaded clothes pin, the clips tapered, serrated jaws are forced together by a spring to grip an object. When manufactured for electronics testing and evaluation, one jaw of the clip is typically permanently crimped or soldered to a wire, or is bent to form the inner tubular contact of a15 mm  ~ 4 mm female banana jack, enabling quick non-permanent connection between a circuit under test and laboratory equipment or to another electrical circuit. The clip is typically covered by a plastic shroud or “boot” to prevent accidental short – circuits. Package include : 1x Battery Clip Pair Category: Arduino Accessories
