hi guys,
i try to make an automatic transfer switch dc for router 9VDC / 0.6A here. I want to switch automatically the power source from router adaptor to battery(power bank) that i set for power backup. and changing back when the router adaptor get an electricity again.
i can't find the most suit design for this case. i just found automatic switch turn on led when dark, that it's far from i need.
i just thought that 2 relay can operate this, but i dont know the desaign.
please help me to build this, i just try what i can.
