Not sure of actual water resistance as I have not tried that aspect but so far they work for my application. I use them to manually switch 120V low to medium power for a control panel. They are rated for 15 amps, I didn't put in more than 10 amps as that is the fuse rating at the main power input. Seems to work fine, no shorts or current leakage to the switch body. However, for operator safety I put on a switch condom from another switch kit I bought and for this project I will be grounding the case at the switches and potentiometer. Although I haven't done the last part yet and haven't had any problems so far.
