Question

How can one make a electric switch

Answer 1

Dear student,

You can make a switch by

A small block of wood: 8 cm x 4 cm x 1cm,Two drawing pins,Three 25 cm lengths of plastic-coated wire

a 4,5 volt light bulb in a socket,a 4,5 volt battery,a screwdriver

1. Attach a length of wire to each drawing pin. Push one drawing pin into the flat surface of the wooden block. Push the second drawing pin through the eye of the paper clip and also into the block of wood. The two drawing pins should be approximately 1 cm apart.
2. Be sure to keep the paper clip in position with the drawing pin, but in such a manner that it can be swivelled to touch the second drawing pin. This is the switch.
3. Test the switch by attaching the free end of the one length of wire to one end of the battery and connecting the third length of wire to the other end of the battery and the socket of the light bulb

Cheers!!
