Wiring for Transfer Switch

I am creating an outdoor transfer switch for my min split air conditioner. Does anyone see a problem with the attached wiring diagram.

One problem is that you cannot use two switches for the transfer. It needs to be one switch.

With your design..... possibly only one gets switched. If the hot was set to main power and the neutral was set to generator...... you could have 120v on the plug if it wasn't connected to the generator.
