It is best to arrange your limit switches so that they supply HARD signals to the Breakout board under running (or normal) conditions.
In other words, the signal being supplied to the breakout board (BOB) should be either a solid ground or 24v (or whatever logic level is required) supplied by the switches when the switches are in their normal runnning state.
It IS NOT good to have open wiring with a pullup resistor (or pull down) on a BOB input supplying the normal operating conditions. You can have pullup or pulldown resistors only if the normal signal condition is a hard ground or logic high supplied by your switch circuitry.
If you have to have an open circuit arrangement then use that to control a relay which then can supply the hard signal to the BOB. The relay being a low resistance device cannot be triggered by noise or induced voltages on your wiring.
If you accomplish this then any type of wire can be used because a solid ground or solid supply voltage will not be able to be induced into by noise sources.
For those with an electronics background this is called keeping everytihng as low impedance as possible.
In my case all of my limit switches are normally closed and connected in series to the 24v supply. This drives a relay which is then normally energized. The contacts of the relay are connected to the BOB and supply it with a ground for normal operation. If any switches get triggered (open) the relay drops out and only then does the BOB see a high level at it's input because it has a pullup. The pullup is not left to float around supplying the logic input.
By this arrangement the pullup resistor IS NOT used to supply the normal operating conditions. (becasue it is suceptable to triggering by noise).
Regardless of what type of switches you are using there will always be a way to arange it into a low impedance circuit. It may take a relay to do so.
