Hi, I need some advice. I have 2 24V switch mode power supplies. I have a selector switch to select the power supply that I want to run, this is in case one power supply breaks, I can select the other one. I have connected the output of the power supplies together; positive to positive and negative to negative (see attachment 1). I think I have read that there might be back flow of current into the unselected power supply, so I want to confirm if this is an issue. Solution to this I believe is to add diodes (see attachment 2). Just want to check with you guys if I am correct.
