A safety mechanism in a cigarette lighter that utilizes a double-button actuator system. The safety button has an aperture through which is positioned an ignition button. The safety button and the ignition button are adjoined by a flange such that when the safety button is depressed the ignition button is also depressed. The safety mechanism also includes a stopper which limits the downward movement of the safety button. Thus the safety button translates downward sufficiently to operate the fuel-release lever opening the fuel-discharge valve. However, in order to activate the piezoelectric unit the ignition button must be depressed below the level of the contact surface of the safety button.
