The double pole double throw one can switch 2 wires between 2 separate circuits. Such as 2 lines from a turbine switching between batteries and a dump load or short for parking.
As far as using it to switch AC circuits, I didn't see any UL approval on it so its certainly not going to meet code for AC. From a purely "can it do it?" angle, it probably can.
I hesitate to just say "yes" not knowing your knowledge of electricity and circuits. I would use it to switch between AC sources but I have decades of experience in several electrical fields and the confidence to know what is going to work and what is not going to work.

I don't know if knife switches are allowed in lower voltage systems. I suggest you talk to your local code inspectors to find out if they'll allow this switch in a code-approved DC installation in the way you plan to use it. No UL might mean no code signoff, which means no fire insurance, even if the switch would be better than the stuff you can buy for the big bux.
(On the other hand if they WILL allow it for 50 volts and below I'd MUCH rather have that shroud than an exposed knife switch. Much less likely to have a nasty short if something gets dropped on it.)[ Parent ]
