Drehriegel / Rotary Latch with magnets

I designed a simple but yet effective rotary latch which snaps into two positions by using three 5 x 3mm magnets (two go into the base, one for each position; one goes into the latch). The rotary latch is mounted from underneath a board with two countersunk screws

I didn't have to glue in the magnets as per design they can't fall out.

The latch snaps into place and sticks. If you want you can use the little plate to make the mechanism of the latch in its base even more secure.
