cutover time is not quick from A to B
Considering returning this item as I do not have a solid answer from seller on what the two leads are from coming from middle of the device. This device will switch fast from B (backup) to A(priority): B is 12VDC source. A is 12VDC source. When A is off and then turned on, this transfer switch cuts to A(priority) power with an insignificant slight glitch or flicker in the power. When switching from A to B by turning A off, there is a full cutout of power such that the load drops out and back on. If using as backup for a power outage, this will reset and device connected on the load or output.

fast switching
This is great for diy projects. It is fast switching. This gives you easy access to automate your power plan. I set it up so that when I have solar coming in it uses that but once the sun is gone it switches to grid power. That gives an automated way to use solar every time its available and not have to micromanage it. If you want to have power switching, give this a go. Be sure to read the specs so that you have the right voltage range for your application.

What is "failed" criteria? Is it 0 volts? 10 volts? A dead 12 volt battery still has voltage.
ok
