Slightly disappointed

This switch is rated for very heavy use, which is good. The problem is that with a plastic cover over the switch button, no matter how hard I press it, the switch resistance below 1-3 ohms cannot be achieved. With a 10 amp load, that means the switch is drawing 10-30 watts of power and discharging most of the 6 or 12 volt supply voltage onto itself. Removing the plastic cover from the switch solved that problem - with a resistance very close to 0 ohms - but it's no longer waterproof.

Pros
