Fast Wire Cable Connectors Spring Splicing Wiring Connector Push-in Terminal Block
Better than the screw type junctions, will never let go of the wires! No screwing, no twisting of wires, no wrapping around, no slips!
Raise the orange clips till they click, insert the wires by pushing them in the holes till you feel resistance, keep you fingers away from the orange clips once you decide to lock it, they kinda snap. Very well made, good price for a great quality product.
