How can i very simply and cheaply solder in something that will turn the battery power off after a few minutes of non use? Answered

I have next to no expertise or electronic "language" skills. I am a grandfather making a rocking star wars toy for grandchild. It will have several buttons that turn on tiny motors and/or led lights. I can't rely on him turning them off at 2 yr old. How can i very simply and cheaply solder in something that will turn the battery power off after a few minutes of non use. I see this feature in a lot of toys that sell for less than $10 so their must be a way to do this cheaply, whether tearing apart a toy ( i dont know what specifically to look for inside) or use some of these parts you mentioned in this project. Also were would i get these parts. Try to not use language beyond my understanding. I have a lot of excellent skills but electronics is an are I am very limited. I can hook up a button to break a circuit to a light. LOL Thanks

ps. 4.5v (3 AA battery power)

These toys have the required things to turn the power off build in.
Adding this feature is usually a bit more complex, especially if there is only 4.5V available.
But why not go the simple route of using push buttons instead of switches?
This way there is no power use unless something is indeed activated.
