I've owned my trailer for 5+ years and have never used the battery disconnect switch because we use the trailer everyweekend, even in the winter.  Well, yesterday, I hit the switch by accident and it killed the 12volt system in the trailer, which is what it's supposed to do.  But, when I hit the switch again it won't turn the 12v system back on.  The red light on the switch ligts up and then goes out.  I can here a click and then nothing.  Now I'm really frustrated.  Can anyone possibly help me out and tell me what I need to do or look for?
