Abstract
An ignitor comprises an ignition coil unit mounted to a base and a control unit disposed on the ignition coil unit and electrically connected thereto for controlling a primary current to the ignition coil unit, which includes a base plate attached to the base and a crank angle sensor for detecting the turning angle of an engine crank shaft. The ignitor also comprises a rotary shaft rotatably supported by the base for rotation in synchronization with the rotation of an internal combustion engine which extends through the ignition coil unit and has a distributor rotor on an extended end thereof. The control unit further comprises a power switch package having a mold resin which hermetically molds therein a power transistor and an integrated controlling circuit into a sealed package. The power transistor interrupts an electric current flowing through a primary coil of the ignition coil and an integrated controlling circuit controls the power transistor.
