Mains Transformer Switched Adapter
I hate wiring mains transformers to terminal blocks in order to connect a power switch and fuse in series with it. This solves the issue, and allows two transformers to be switched off of the same switch! This should be good up to 3A on the primary, however, I would NOT recommend connecting a toroidal transformer (ONE) above 160VA. As this PCB is at mains potential, basic electrical safety should be followed. Keep fingers away from PCB when in operation and all spade terminal and connector connections should be INSULATED. When mounted in the project/device, it should really have a plastic box/cover over the top of the PCB to prevent accidental contact.
I will not be held liable or responsible for users of this PCB's negligence.
