NO! DO NOT connect cobs to AC power!!! The switch should be on the 120VAC power line to the driver.Does this look right? I think it is but don't trust myself.
What parts you got on the output side of the driver? Personally I would fuse and switch the AC side of the driver not the DC output side. They make switched fused and filtered ac plug ins might be a better option.
I freaked out when I saw a 120VAC connector on the DC side. A 120VAC plug should NEVER be used on low voltage dc wiring. Your drawing shows black and white wires connecting the driver to cobs, the DC output wires from the driver are black and RED.I think that the ac power is going into the the driver, right? the other plug shown is for connecting another fixture.

Use an on/of switch rated for 110v and 20a like this View attachment 4067460
or this fused oneView attachment 4067463
both on ebay
View attachment 4067506 For the daisy chain feature, split the AC at the input/switch with a piggyback spade connector and connect one side to your second input plug. That plug will always have power. With the other AC line you'll have, jump to the switch, then connect the driver to the other side of the switch. I chose a combo input/switch without the fuse. There is no switch, plug, or fuse on the DC side, just the LED load.
they make extension power strips with fuses and such nowadays too.
