I am having a heck of a time getting my limit switches to work.

My computer is giving a solid 4.9v through the printer port and then coming out of the rutex board I am getting a whopping 1v through the limit switches

5v limit switches I know are bad enough with noise as it is but with the measly 1v I am getting from the mother board I get a false switch trigger just by thinking!

any help would be great!

IE how to get that 1v up to the target of 4.9v

or if there is a way to change to 24v without massive changes that would be awesome too!
