Child lock for furniture.
Can be attached via double sided foam tape or screws

In armed state the small magnet lifts main magnets as a spring and lifts the hook.
To disarm just enclose the magnet "key" at about 5cm and this overdrives the "spring" magnet.
To permanently disarm - just remove the spring magnet from the bottom of the lock.

What you need for one lock (BOM):
- 1 inch of 3mm rod. I used a steel one.
- two 6x3 mm magnets
- one 4
