Understand how tilt switch works with everyday things.

Tilt switches are used in vending machines, thermostat and other devices.

Tilt or movement is detected using some mechanical arrangement or mercury.

Mercury is the only metal in liquid state. Its density is 13.5 grams per cubic centimeter. It is a good conductor of electricity as well. A tilt switch is an electrical switch that opens and closes a circuit. It contains a small amount of the liquid metal mercury. It connects metal electrodes to close the circuit.

Now-a-days mercury is not easily available. It is difficult to handle as well. Handling mercury is hazardous as well.

We will build tilt switch from corrugated sheet. Marble is used to detect slope. 20 gauge bare copper wires are used for connection.

This winding ensures that circuit is closed when marble moves to the right side. Circuit is broken, when marble moves to the other side.

We can find the slope of the plane by placing this on the surface.

Steel ball can be used to achieve the same result.

Try building same which shows which way it surface is inclined.

Do try this at home !
