You are probably correct in thinking that the neutral need not be switched. The manufacturer may have had some reason to prefer that the motor is fully isolated though so you should check the motor units to see.

Figure 2. Possible solutions using standard domestic single-pole, 2-way switches. Both circuits prevent attempting to run both motor coils simultaneously.

You should have no difficulty in obtaining a changeover switches and wiring them as shown in Figure 2.
