It is a perfect example. In reality, an H-Bridge is just transistors performing the same operation, just solid-state.

I guess the spark could be a possible recruiting tool -- that, only if the correct precautions are taken! It's not the best idea to try this at home, at least if the voltage is greater (or lower) than 0v

I think that that is actually quite a typical setup to introduce the system.

However, it's pretty cool how I still use that setup all the time. Just take a DPDT switch. Connect the middle pins to the motor. Connect one side of the switch to the battery. Connect the other side to the battery too. However, on the second side, reverse the polarity. If the switch is on one side, the motor will spin in one direction. Switch the switch and the motor will switch directions!

I am wondering what that was even meant for. Is that supposed to be a motor tester of some sort? It seems quite dangerous!
