ABSTRACT:
A magnet latch applying magnetic force for opening and closing the upper and lower cases is provided. The magnet latch includes a push button, a sliding block, a magnet, a magnetic hook, and an elastic member. To close the upper and lower cases, one moves the push button to slide the sliding block to one side. The magnetic hook is attracted by the magnet to move upwards. Once the magnetic hook attaches to the magnet, the push button is released and the sliding block moves toward and holds the magnetic hook, so as to achieve the purpose of magnetic latching. On the other hand, to open the upper case, one moves the push button to slide the sliding block to the other side, thereby opening up the upper case. Due to the weakened magnetic force and its own gravity, the magnetic hook returns back into the lower case.
