Hi all,
My son has expressed an interest in electronics (he's 6) as a friend gave him a bag of various 20 switches that have led bulbs in them.
This sort of switch:

I have purchased a ABS project box and a bread board and wires, what we want to do is add as many switches to the project box as possible and power them with a 9v battery. We're going to label the switches 'Launc', 'Missiles' 'Smoke Screen' etc.
My question is where should I place the resistors? What size would I need? I want to avoid blowing the LEDs but we would like more than one lit at the same time.
Many thanks
Steven
