I am designing a changeover circuit that switches the load from one grid station to another. I was thinking about wiring two spdt relays in anti-parallel to create a dpdt switch.
The schematic at the end although a different application, best captures the question that I am about to ask.
My question is that can this cause a short circuit/connect the two grids during the small time period when the relay is switching. Does it matter if I am using a mechanical or a solid state relay? Is there any way to avoid this?
