For example, in one embodiment, each lead connects a corresponding contact to a plurality of terminals to allow the controller to supply to signals to the terminals without requiring a separate contact for each terminal. However, to assure that the components can each be controlled independently of the others, the leads are also arranged so that each component's terminals are connected to a unique combination of contacts. Thus, the external controller can activate a selected component by supplying control signals to the combination of contacts uniquely associated with that component. | 2010-06-24 |
