invert Push Buttons

Hello, i hope somebody can help me.

I am working on the 737 Saitek Throttle. I have printed all parts and now I am starting the wirering.

Now I figured out that I bought the wrong Push Buttons. I have Push to break buttons instead of push to make buttons. The circuit is closed when the button is not pressed and it breaks the circuit when I press the button.

Is there a possibility to invert this in the arduino micro pro?

I just don´t want to wait 2 weeks for other push buttons. ;)

Thanks in advance for your help.
