Liyafy 30A 3.7kW 3 Phase ON/OFF Self Lock Push Button Power Switch Mechanical Equipment Control Station 2Pcs

The switches work well although the enclosure is very small and I'm sure not meeting code space requirements in the USA.

It was used to replace a contactor on a small 3-phase machine. I bought two to have a spare. The metal used for the box is so thin, you could crush it with your fingertips. The button controls are in the lid, which wouldn't be so bad, but the box itself is so flimsy that I doubt it will stay in one piece very long, with a tiny screw and a questionable catch notch to hold everything together as your idiot employees mash the buttons carelessly. It's definitely worth the money: less than 20 bucks for two, but if you need something robust, this ain't it.I wouldn't try wiring anything bigger than 16ga wires into it, and nothing with any chance of tension on the wires. There really isn't space for cable clamps; use rubber grommets. The plastic ones it comes with are pretty useless, even if you can get them to stay in the holes.

ABSOLUTE HAZARD DO NOT USE.Ive been using this switch for maybe a week now and the contacts have already discolored and melted which ruined the latching system. Machine got stock ON. This is on a machine that is well under rated for this switch. Extreme fire hazard and very dangerous. IF YOU VALUE YOUR LIFE OR MACHINES DO NOT USE THIS SWITCH.
