PIEZOELECTRIC IGNITION TORCH SWITCH ON SELECTIVELY Russian patent published in 2003 - IPC

FIELD: piezoelectric ignition mechanism for gas lighters, burners and so on. SUBSTANCE: piezoelectric ignition torch will not form spark discharge in case of routine pressure till its gate is not set in action first. Plexor is released to strike piezoelectric system for generation of spark discharge with pressure on button after gate is set in action. EFFECT: raised intricacy of ignition torch of gas lighter which does not require precise match of gate between button and case of lighter. 33 cl, 12 dwg
