Simple use and setup: Connect the device to a standard banana plug, then attach the other end to an insulated wire for quick testing or circuit evaluation. Durable construction: Built with a texture and wear resistant materials designed for long term use. Centered wire contact: Spring loaded double V clamp holds the wire centered for precise alignment and reliable contact with the piercing needle. Insulation friendly operation: The piercing clip set can release from insulated wires without piercing the insulation, enabling non destructive disconnection when needed. Compatibility and function: Designed for use with standard banana plugs and insulated wires in testing, prototyping, and measurement tasks. Performance and reliability: Provides stable, repeatable contact and dependable operation over multiple uses. Use scenarios Prototyping and testing: Attach a signal source to the banana plug and connect to insulated leads to evaluate circuits without stripping insulation. Educational demonstrations: Show how insulated wire contact is achieved and how the piercing mechanism centers on the conductor in a controlled, safe manner. Field maintenance and troubleshooting: Quickly connect to insulated wires to check circuits or diagnose issues without removing insulation or exposing conductors.
