I had dramas with my first switch too. I don't know what the internal design/components are like but in my observations, they appear to be a quite a bottleneck for current.
I initially had a bit of trouble with my winch intermittently receiving enough power to turn, it would just *click* instead.
Admittedly my original battery was a little underpowered in terms of CCA, but when troubleshooting it over a few occasions I connected the power wire directly to the battery and it would fire fine, go via the isolator again and it would cut out again. I did this back and forth on several occasions with consistent results.
Regardless of the battery, the isolator was demonstrably a weak link in the chain.
I since upgraded to a higher CCA battery, put a bigger ring terminal on the winch lead and it has been flawless since.
