Langing Gear Issue

I went to hook up today and when I went to use the switch to raise and lower my landing gear it did not work. No hum, nothing. I go the remote that came with my trailer and that worked which allowed me to raise and lower the legs. To me, it sounds like the switch is bad. I took off the switch and there are 8 wires going to 6 terminals...two of them have tow wires linked together. Anyone know how I can check my switch. I tried making a jumper out of a piece of wire but it did not work. Any ideas, suggestions, etc? Thanks
