The big light bulb heats a bi-metalic strip. When the strip bend enough, it breaks the circuit for the large bulb. When the strip cools and straightens, it turns on the large bulb again.

The big light bulb heats a bi-metalic strip. When the strip bend enough, it breaks the circuit for the large bulb and closes the circuit for the small bulb. When the strip cools and straightens, it switches off the small bulb and turns on the large bulb.

 

 

The ball begins at the top of the long end with potential energy. At the bottom of the hill, the energy is all kinetic. At the top of the loop and the top of the short side, the energy is split between potential and kinetic.
