Fuse keeps blowing

[govols23]

I have 2 switches, the one on the right controls the lights in slide out above sofa. The one on the left i have no idea what it controls as it keeps blowing the fuse when i switch it on. Pics included of switch and fuse box. Any idea what the switch controls and why it blows the fuse? It's #10 in fuse box.....

It would really help if you provided what year, make and model of rig you have.
Only the labeling from another similar unit might help.
The breaker panel/fuse panel is used throughout Forest River, but gets wire$ for different things in every different model.

I'm making an educated guess here,... S/O on Fuse #10 means Slide Out. You said one switch controls the light. If the other switch blows the fuse immediately I would say there is a direct short in the circuit. Without knowing the configuration of your slide I can't begin to guess what the switch controls. I would remove the switch and inspect the switch wiring for shorts and see if the wires can be traced visually. Additionally, with fuse #10 removed you can easily check the resistance of the switch circuit (wires removed), with a multimeter. If there is no resistance then the circuit is a direct short.
