Nichifu offers a variety of quick-lock push-in connectors as well as plier tap connectors that incorporate a stable 2-point contact spring that allows for an easy insertion that doesn't disconnect easily. Push-in wire connectors are installed by inserting a wire into one of the holes of the connector and locking it into place, and feature a release feature that allows you to easily reassemble the system at any time. Our Push-In Wires offer a corrugated conductive plate to expand the contact area with the wire which helps to improve the conductivity level.
