Circuit Blox™ - 3線塊 - E-Blox®

The three-wire connector clicks in securely and makes my circuit builds much cleaner—exactly what I needed for a complicated parallel setup.

Needed one more three-wire piece to finish a circuit and this fit exactly like the ones from the original set. The connection points line up cleanly with the other blocks, no wiggling.

The wire block snapped right into the circuit base with a satisfying click, no wobble at all. It's a single piece, so there's nothing to assemble or lose. My kid's build finally lit up after we swapped this in.
