Abstract
A no-contact ignition control device includes a stop switch which maintains a second switching element at the OFF state so that an induced voltage of a trigger coil triggers a first switching element and shortcircuit a generation coil. A surge absorption element is connected in parallel to the stop switch. This configuration prevents intrusion of a surge current into the ignition control circuit caused by static electricity accumulated on the surface of casing covering electronic parts of the ignition control circuit and surely avoid dielectric breakdown of the electronic parts or malfunction of the circuit by the surge current.
