CuriousGear #03 Light Switch | No AMS, No Supports

CuriousGear: How It Works – #03 Light Switch Ever wondered why a light switch snaps instead of stopping halfway? This is a wall switch cut in half: on the front you press a real rocker (I / O), and through the window you watch what happens inside. A blue PETG spring sits in the red rocker and pushes a plunger onto the yellow contact bridge. Press the rocker and the plunger slides over the bridge's pivot – the "dead point" – and the bridge snaps to the other side. Click: the contact closes and the little bulb window turns yellow (ON). Click again: the bulb window goes dark (OFF). It can never stop in between. ✔ No AMS – 4 plates, 4 colors (gray, red, yellow PLA + blue PETG) ✔ No supports · No screws · No glue – snap-fit assembly in about 2 minutes ✔ Print time: ~2.5 h total (4 plates) · Filament: ~56 g PLA + ~2 g PETG · Tested on Bambu Lab A1 ✔ Every part is pre-oriented for printing – just load the plates and print What kids learn: lever (rocker), spring energy, over-center (bistable) mechanism, and what the I / O symbols on real switches mean. Color key (same in every CuriousGear model): Gray = Frame · Red = Press · Yellow = Moves · Blue = Spring Assembly: 1. Slide the blue plunger into the pocket of the red rocker. 2. Put the yellow bridge on the small axle. 3. Lower the rocker into the frame and onto the big axle – gently push the plunger against the bridge. 4. Snap on the cover. Recommended age 6+ · Adult supervision · Contains small parts – not suitable for children under 3. Inspect before giving to a child.
