Magnetpro Multipurpose Switch Magnet, 660 LB Pull-Off Force Switchable Magnetic System, On/Off Magnet for Lifting, Working&Welding Positioning, Liquid Filtration, Automation, Metal Separation

so i dont use this in a metal shop, this will be your unconventional review haha. i have tested it on 1/2" steel plate though in our yard and itll lift a pretty decent sized plate, i dont know the exact size of it but if i had to guess maybe 5 sq ft. anywho, im a commercial diver in the mississippi river and we rely on magnets in high current to keep us on our work station if theres nothing to clip/tie onto. now the current of the river kicks pretty good some days, and i dont know exactly how much weight i put on this magnet at times but i can tell you that with it put on a rusted and scaled up piece of 5/8" steel (probably closer to 1/4" and all the way down to 1/8" in some spots) ive been able to hold my body weight (roughly 160lbs) in up to 10mph currents, on this magnet mounted sideways (visualize mounting it above or to the side of your body with all the weight pulling this magnet to the side, which it is strongest when pulled directly up)

I have the smaller version and it actually holds better. Almost impossible to turn the magnet on, even with the handle. Go with the smaller version or a different brand.

I didn't need this, so I can't rate it on application. I wanted one of these just because. I've only tested this on fairly thin metal, but it's crazy strong. With thicker steel I'm sure it would my even stronger. Just for seeing if it works... this absolutely "works". It is slightly magnetic while off, and insanely magnetic while on.

These affordable magnets (compared to MagSquare magnets) are great for fixturing and holding. They work well, but the handle can be a little problematic at times where they do not want to complete a full turn to fully engage the magnet. The two flat sides and two rounded sides aren't as versatile as MagSquare magnets, but for the price you can purchase several in order to get more flat sides and spend a little more time configuring your fixture. The rounded sides and the notchy mechanism are minor issues so it still gets four stars for the value and effectiveness.

Magnet holds well when pulled directly away from metal. However, magnet will easily slide on metal. If you were to pickup a metal sheet with magnet, it could slide to edge of sheet and break free. Magnet needs a way to be held from sliding around.

Great

I'm a little underwhelmed - I place this on the steel Metro Water plate in my front yard and yes, I can lift the 17-20 pound plate but it takes next to no effort to detach it. I wouldn't carry the plate with this for fear of detaching. I tried it on my metal door, ok. Cast iron 1940's staircase, good but still using very little effort to remove. I mean were I to guess I'd imagine it's topping out at about 60 pounds that it can lift and yeah, I'm sure I've got impure iron that I'm trying it on but man it feels cheap in comparison to even my windshield washing neodymium magnets.

Works as advertised, and like one of the other posts I bought these to avoid the $900 magswitches for my power feeder. The folks saying it only has 20lbs of holding: you need to PRESS and TWIST the handle to engage the magnet. It seems to have 3 settings: off, "weak hold" and ON full hold For the people saying the handle is hard to turn: you need to PRESS and TWIST

Der Magnetpro Mehrzweck-Schaltermagnet überzeugt vor allem durch seine enorme Haltekraft. Gerade wenn es darum geht, schwere metallische Gegenstände sicher zu fixieren oder zu heben, leistet dieser Magnet hervorragende Arbeit. Die ON/OFF-Funktion ist besonders praktisch: So kann der Magnet punktgenau eingesetzt und genauso einfach wieder gelöst werden. Das funktioniert überraschend gut! Ein weiteres Highlight ist die Vielseitigkeit: Nicht nur für Schweiß- und Hebearbeiten eignet sich der Magnet ideal, sondern – so wie bei mir – auch für den Alltag in der Werkstatt. Kleinere verlorene Metallschrauben oder Muttern lassen sich damit spielend leicht wiederfinden und aufsammeln. Die Verarbeitung ist solide und das Handling insgesamt sehr bequem. Fazit: Ein wirklich starker und zuverlässiger Magnet, der in keiner Werkstatt fehlen sollte. Für unterschiedlichste Anwendungen bestens geeignet und auch für das schnelle Aufsammeln von Kleinteilen ein echter Mehrwert! Absolute Kaufempfehlung.

Great mechanical switchable magnet. Exceptionally strong when switched on and completely inert when not. Has a good holding capacity. Used a few of them integrated into theatre sets where items have to fall off a wall on cue, and works perfectly for this purpose where budget or safety means an electromagnet isn't suitable for the same purpose.

Cet aimant ultra-puissant me permet de monter des dispositifs de mesure sur mon marbre en fonte avec la garantie que rien ne bougera, même avec un porte-à-faux très important. Afin de faciliter la mise en place du dispositif, il est possible de placer le commutateur ON/OFF en position intermédiaire pour obtenir une force d'adhésion médium. Des filetage M5 et M6 positionnés sur les différentes faces de l'aimant permettent de facilement y fixer les accessoires voulus. Attention, si l'aimant est tenu dans le vide ou positionné sur une surface en métal de faible épaisseur, il est très difficile voire impossible de faire tourner le commutateur et d'activer l'aimant. Contacté à ce propos, le fabricant m'a confirmé que c'était un comportement tout à fait normal de cet aimant et en aucun cas un défaut.

Qualité au top

Non l'ho ancora provato concretamente ma mi sembra molto potente e molto ben fatto, molto bello!
