The piezoelectric lighter for gas appliances, comprises a piezoelectric module struck at one end. A case of insulating material contains the module of which the end opposite that receiving the impact is connected to an electrode emerging from the case. A hammer lever, also of insulating material bears a percussion hammer, and pivots around an axle of the case on being subjected to the action of a spring. Electrical continuity is provided between the struck end and the metallic mass of the appliance on which the lighter is mounted. High voltage is generated and a spark flies from the burner due to the electrical continuity assured by the following circuit: electrode (2) module (1) and striker, hammer (3) spring (20) plate (8) mass of the domestic appliance or the like and burner. |
