REFLECTOR: Switches

[Scott Derrick]

I have a Velocity circuit panel in my plane with the rocker breakers.

While they are compact and cheap(not expensive),  they are not a 
breaker/switch.

Is there a replacement that is a breaker switch?  Not being able to switch 
off a section of the electrical circuit except by using the master switch 
is a serous design fault.
