I have found an effiecent means of creating the number of contact closures i need :lol: . Last night i had another thought. If button 1 and button 2 are pressed at the same time, this would create the contact closure for button 3 right?.... does anybody know of a way to lock out a series of swtiches so that only one can be pressed at a time?

You can make 256 closures,
With combinations of the ports (diodes)
