1 switch 2 battery 3 resistor and 4 ground. Hardware components power sources ground chassis terminals some wires of course. The electrical symbols will not only show where something is to be installed but what type of device is being installed. For example a switch will be a break in the line with a line at an angle to the wire much like a light switch you can flip on and off.
