The two elements 23 and 23A are completely encased or encapsulated by a resilient electrically insulating material 28 such as rubber or plastic with the exception of the metallized outer ends 24 and 27 which are grounded to the casing 1 through contact with the lever arm 19 and preloading screw 29. The ends of the piezoelectric elements are metallized at 24, 25, 26 and 27. The free end of arm 19 is in engagement with transfer piece 22 in contact with one end of two stacked piezoelectric elements 23 and 23A. The opposite end of arm 11 is mechanically linked by connecting member 13 to arm 14 pivotally mounted at 15 which in turn is linked by connecting members 16 and 17 to arms 1S and 19 pivotally mounted at 20 and 21. piece 8 is provided with a plunger 9 which passes through sleeve 10 into casing 1 where it is connected to one end of arm 11 pivotally mounted at 12. Mounted upon the casing 1 by support 6 is a snuffer 7 actuated by a manually depressible fingerpiece 8 in the manner of conventional lighters. In fuel transferring contact with the absorbent material 2 is a wick 4 which extends through and terminates above wick tube 5. The bottom of the casing 1 is provided with a filler opening sealed by closure screw 3. 1 of the drawing, one embodiment of the invention is illustrated as applied to a lighter having a casing 1 of general rectangular cross section, the fuel chamber within the casing being filled with absorbent material 2 such as cotton or the like which is saturated with lighter fuel.
