When the ball falls to the cup lever, the lever is operated and the ball on the horizontal rail rolls to another device.
It can be used between a C-4 waterfall rail and a D-1 swirl tower, and can be used with other devices.
You can learn about gravity, potential energy, and inertia by making a double switch.
Step 1&2. Create the body and rails
① Fold the body along the fold line and fix it with snap buttons on the lower part of the body as shown in the figure.
① Fold the rail along the fold line and secure the bottom three sides of the rail with snap buttons as shown in the figure.
② Secure the rail guard by inserting it into the groove on both sides of the rail.
① Insert the rail into the groove in the upper part of the body. Align the groove of the body with the rail and insert the white rod to fix it with the red rubber ring.
① Fold the levers, lever support, and lever guards along the fold line.
② Fold the bottom of the lever and secure it with the snap button as shown.
③ Fold the lever guard and fit it into the groove on the top of the lever.
④ Fold the lever support and secure it with a snap button.
⑤ Place the lever on the lever support and align both grooves. Insert the transparent rod(short) into the support and fix it with black rubber ring.
Step 5. Connect the lever to the rail
① Fit black rubber rings on both ends of the transparent rod.
*Adjust the gap to be 15 mm from the end of the transparent rod.
② Connect the transparent rod between the lever and the rail.
③ Fix the transparent bar by inserting the black rubber ring on the top of the rail and the bottom of the lever.
Step 6&7. Complete and operate the double switch
① Adjust the rubber ring of the transparent rod so that the rail is horizontal and the lever is adjusted to raise the cup side.
*Insert the cup into the groove of the lever and fix the beads to the groove on the horizontal rail.
① Put beads in a cup to see if the beads on the rails roll.
② Observe the change in the position of the lever and the rail.
