I think it's pretty safe to assume the moderators can determine that this is talking about a small motor, not in an automobile....

i want to add something to the circuit below that turns the circuit on and off by the press of a button

Do you mean:
1. Turn the power to the circuit On and off with a push button?
2. Make the motor run regardless of the sun light?

Using a push button to turn on the motor is easy but not the power....

You assume a bit much, whether it is a motor or not, you are apparently describing a auto modification, this is the thing that is the violation, not what the modification is.
