Tilt switches use a metal ball or a drop of mercury to sense if an object is tilted. The ball or the drop connect two metal contacts. If the object is tilted the connection is open.

This simple tilt switch is easy to build. All you need is a M5 washer (11 mm outer diameter) and two pieces of 1,5 mm^2 single strand wire.

The sensor works in all directions but I noticed that (seen as in the pictures) the forward/backward direction is the most reliable.

Keep in mind that this switch is not suited for the use with high power electricity. It works well as a sensor (e.g. for Arduino) or to switch with a transistor.

Use a file to smooth the glue surfaces. Check if the wires fits in the holes. Make sure the outside of the washer is smooth. Remove oxidations and fat.

Put the washer (without touching) in between the 3D printed pieces and stick the wires in the holes to align both halves. Use CA-glue to connect both halves. Make sure not so get glue on the washer or the wires.

Remove the wires and solder the connection wires to them. The heat of the soldering iron will cause the copper to oxidise. Use sand paper to remove the oxide layer. Don't touch the copper wire! Stick both wires back in the holes. You may use a thick glue to keep them in place. DO NOT use CA-glus (as I did on my first print), it will cause the switch to malfunction! After the glue dried test the switch.
