ABSTRACT:
Disclosed is a piezoelectric type gaslighter equipped with a thumb-latch for preventing an inadvertent fire which may be caused, for instance, when a child plays with a gaslighter. A gaslighter according to the present invention includes an intermediate casing and a piezoelectric unit having a movable operating part. The intermediate casing has a cross slot opening with a thumb-latch slidably fitted therein whereas the movable operating part has a longitudinal slot groove. The piezoelectric unit is properly inserted in the intermediate casing so that the longitudinal slot groove of the movable operating part intersects the cross slot opening of the casing. With this arrangement when the thumb-latch is displaced to the crossing at which the longitudinal slot groove intersects the cross slot opening, the movable operating part can move to strike the piezoelectric element for producing a small flame. Otherwise, the movable operating part is latched.
