How to Make a Switch?

You will use:

     Electric lantern cell
     The bulb with wire attached that you just made
     Bell wire
     Strip of metal
     Block of Wood
     Nails
     Hammer

Do this:
1.Take a piece of metal 4 inches long and 1 inch wide. You can cut it form a tin can if you are careful not to cut yourself. Use the kind of scissors called  tin snips. Wear gloves.

2.Nail one end of the metal strip of the block wood. under the end of the metal.

3.Do not hammer either nail all the way down in the wood.

4.Bend the free end of the metal strip upward so that it is not resign on the nail beneath it.

5.Now you have a switch.

6.Connect one end of a length of wire to either terminal of a dry cell. Connect the other end of the wire to nail under free of the metal strip.

7.To connect a wire to the lantern cell, just twist the bare end of the wire around of the strips on the top of the cell.

8.Be sure to scape the insulation off ends of all the wires you see.

9.Using the lantern-bulb-and-wire-device you just  made, connect one end of wire attached to the bulb to the other terminal of the dry cell.

10.Connect the other end to the nail holding the strip of metal in place.

11. Now place the switch

12.If you have made all the connections right, the circuit is loaded, and the bulb will light.
13.Don't hold the switch down for more that few seconds. The dry cell will wear out.

14.Save this switch. You will probably use it many times.

15.A switch is a convenient way to open and close a circuit. It is easier that connecting and disconnecting wires.

16.Use your switch only with a dry cell. Don't try to use switch with any household electrical appliances or lights. YOU MAY BE KILLED.
