These electrical connectors facilitate temporary connections between a piece of testing equipment, such as a multimeter or oscilloscope, and a circuit under investigation. They consist of a wire terminated at one or both ends with spring-loaded, toothed clips. The clips provide a secure and easily detachable grip to terminals, wires, or other components within the circuit, enabling signal measurement and voltage application without permanent soldering or wiring.
The utility of this connection method stems from its versatility and ease of use in prototyping, circuit debugging, and educational settings. Their quick attachment and detachment capabilities significantly reduce the time required for circuit analysis and modification. Historically, this type of connector emerged alongside the development of electronics, offering a practical means to bridge electrical components before the widespread adoption of more permanent connection methods.
