Review on RKURCK 12V 32V Circuit Inverter Waterproof Industrial Electrical by Justin Hollins

Seems to work well as a switch, haven't tested under load to see if it blows at the correct amperage. The top cover (with the rating printed on it) is easy to knock off. It's pressed around the unlock button and has two thin plastic bars holding it next to the yellow lever. Pry or hit it and the cover will come off. Then you lose the red button. The case is solid, but finding screws that match the captive nuts for mounting took some time.
