A magnetic catch is a latching mechanism that uses a magnetic force to hold two objects together. Most magnetic catches consist of an ironplate and a magnet. The magnet is installed on one object, whereas the armature plate is installed on the other object. After installing both components, a magnetic force will hold the two objects together. You can then separate the joined objects by pulling them away from each other, thus breaking the magnetic force.
While there are other hardware solutions available to hold objects together, magnetic catches offer several benefits. For starters, they are easy to install. You just have to install the magnet on one object and the armature plate on the other object. Most magnetic catches feature holes for screws. You can drive screws into the magnet and armature plate to install them on the appropriate objects.
Magnetic catches are long-lasting. Magnetics can and do lose their magnetism — but this isn’t something that happens overnight. It can take many years or even decades for a magnet to lose its magnetism. As a result, magnetic catches are long-lasting.
