HO number 4 switches

[cwex]

Can I hook up 2 number 4 switches together in order to connect two ovals of track and utilize my Bachman ez command system

Yes you can.

But if your layout can support it, I would use the #6 crossover instead:  The turnout curves are gentler and will support larger rigid wheelbases.
