I really hate being a nit-picker, but just to keep everyone straight: That arrangement of diodes provides OR logic, not AND. In other words, the circuit is activated when one OR another of the switches is closed.
To provide an AND function, switches merely need to be wired in series.
You knew all that, but some readers may not.
