If its simple mechanical switches you are using then all you need to do is connect one wrie from the first switch to your breakout board ground, the other wire goes to one wire on the next switch, the other wire on that switch goes to the next switch and so on, when you have all the switches connected you will be left with one wire which you then put to an input pin on your breakout. You need to have normally closed switches, that way Mach sees everything as normal until one or more switches are broken, it also acts as a safety feature as any wire that breaks will trigger a limit activated signal in Mach.
