Hi guys,

I'm going crazy trying to find the right solution to power a circuit with 3 different 5v supplies.

My initial idea was to use 2.54 jumpers, but it is not the correct way to handle a 3Amp current with them.

My second idea was to use 4 screw connectors like the Keystone 7770 M3 and move the blade that interconnects them according to the power supply to be used. This might work well as they can withstand a current of 15A, but they take up a lot of space.

Can anyone help me find a less bulky solution?

 

How able this type of "Quick fit" pcb-mount terminals to fit 1/4" crimp terminals? The picture is from Keystone.

 

There is also 2.54 size terminal blocks, if you want the jumper version.
