EFIS, EMS and Servo wiring

[dft46]

Please can I have some advice? I am buying a D100, D120, AP74 and 2 SV32 servos for my Sportcruiser. I cannot find any documentation on how to switch them - ie separately or independantly. I am proposing the following:
Switch and circuit breaker for D100/AP74
Switch and circuit breaker for D120
Switch and circuit breaker for the two Servos

Is this an overkill? Can I for example have just one switch and CB for the D100, AP74 and D120?

I would appreciate help and commments.
Thank you

Exactly how I did it, if you need to isolate anything it does not take all the others out at the same time.  

I did however put the AP74/HS34 and servo's all on the same breaker.
