Each Hammond key has 9 switches, one for each of the nine harmonics on the drawbars. There are 9 conductive bars running along the back of the keyboards, and these are the busbars. "Busbar" may also refer to the wires connected to the actual busbars. As the key is pressed, each switch connects the proper tone for that harmonic on that key to its corresponding busbar. The busbars are then connected to the drawbars, which control the level of each harmonic.
