All sounds confused. Use one transformer to supply the lot, and it will
need to be a toroidal, not an electronic one, since the tronics have
minimum load requirements that youll go below.

The toroidal transformer plugs in the mains, theres no reason to add a
CU way for it.

Switch everything on the LV side, switches wherever you want them.

To determine ratings of transformer we need the specs of the lights:
power, voltage and type. The kit says halogen, you say LED. Kit says
10w, you say 10v - proper info required.

Since everything will be wired at LV, life will be easy.
