Hello-

I'm planning to install a bunch of LED lights in my kitchen cabinets. The idea is to have a small LED strip turn on automatically when opening the cabinet door. I've found a 12v LED strip that can be cut into 30cm long sections that will be perfect for my application, along with some magnetically activated door switches.

My question is:

A) Is it better to run 120/240v through each cabinet door switches, and then go to the LED transformer (driver) and finally the lights?

or

B) Or, is it better to place the door switches on the low 12v voltage side of the transformer (driver)?

I made a simple drawing to show you what I mean.

My thoughts are that A has the advantage that the transformer is completely isolated when the doors are closed. B has the advantages that it is safer (is it?) in that the switches are 12v in case someone pulls out a wire accidentally. Additionally, B would be cheaper to install because multiple lights could share a single appropriately dimensioned transformer instead of needing separate transformers for each light.

Thanks for any insights!!

PS: I won't be doing this install myself, I'll use a licensed electrician. I just want to have a plan and understand the issues beforehand.
