ABSTRACT:
An electronic ignition control device employs two switch devices (e.g. mechanical contact breakers) operating at different instants to control initiation and interruption of current flow in the primary winding of the ignition coil. The coil current is controlled by an output transistor which is biased to conduct but which is switched off by an input transistor when a spark is required. The input transistor is controlled by the two switch devices so that opening of one switch device initiates primary current and opening of the other interrupts this primary current.
