remove that switch box and put a 4x4 or 6x6 junction box where that is,
then just extend those wires down from the new junction box to wherever you want to mount the switch/fuse box,
so you will have 4 wires going into the new junction box, the 2 existing ones that are there, and two new ones going to your switch box
