After listening on the sounds on the DX Fourze Driver. Below is a list of the switches that has and will be featured on the TV series Kamen Rider Fourze - all 40 of them. There are some mentioned switches here that are yet to be presented but I've added a few tidbits and rumors that came with it.
Below is an appendix where each switch goes/forms to which module in Fourze's armor:
Circle - right arm
Cross - right leg
Square - left arm
Triangle - left leg
Here we go.
