The current monitor limits the current draw of the outputs to the motor and gearbox."
You don't have to be an electronics wizard to get the gist of that. The timed period is 2.5 ± 0.1 seconds. The maximum current draw is 3.2 ± 0.1 amps for 500 ± 20 mS.
See how much technology and effort goes into the design of a toy.

Simon I should say thank you but sorry still don't understand. I've even done a Google search and am none the wiser.
I assume from the post the switch plays some part in this
