كتلة مفتاح لـ Circuit Builder

Bought this as a spare so my kid could keep building without tearing apart his existing circuit, and it clicks in just as firmly as the one that came in the set. The little lever has a nice positive snap so you can tell when it's on versus off.

The switch snaps right into the block setup and finally lets my son turn his little circuits on and off without yanking wires. Being a single piece, it just clicks in with the rest of the set. He's been building for an hour straight.

Bought this as a spare for my kid's circuit kit and it clicks in just as smoothly as the originals. The little toggle has a satisfying snap to it, and the plastic feels sturdy enough to survive being yanked apart a hundred times.
