Abstract: The present invention relates to a lighter which a user actuates by at least two different modes of operation. In the first mode, a plunger member is positioned to allow a biasing member to oppose movement of an actuating assembly so that a user releases fuel and ignites the lighter only if a high-actuation-force is applied to the actuator. In this first mode, the lighter resists operation by unintended users by requiring a user to have a predetermined level of strength to actuate the lighter. In the second mode, the plunger member is moved to a different position so that the biasing member does not oppose movement of the actuating assembly to the same extent as the first mode so that a user may release fuel and ignite the lighter if a low-actuation-force is applied to the actuator. Moving the plunger member from the first position to the second position preferably requires the user to have a predetermined level of cognitive abilities and/or physical characteristics in order to resist use by unintended users.
