sorry i just realized how the setup is one. are the switches NO or NC? i would try to wire them in parallel and use M558 P5 they will need to be connected to the z probe port. but a construct would allow the printhead to move. this would not be beneficial for the print quality.

@veti Yep that was the reason! Thanks a lot!
