T h e r e are m a n y kinds of switches. Some look like this. 44 45 2. How can a bell be connected with two dry cells so that it will ring? Use cotton-covered copper wire. Connect two dry cells together. Be sure you connect a positive terminal and a negative one. This is important because electricity goes from the positive to the negative.
