how to make a simple switch
today I would like to show you how to make a simple switch. you need every thing I said in the last section, and new parts: an index card,brass brads,and a paper clip. do the same from the last time,but put the brads into the index cards unfold the bottoms on the brads then tape them down,put the paper clip onto on of the brads shut the paper clip then it should work. and you can show anyone, or do it with them.
