Abstract
Abstract An impact type piezoelectric mechanism for use in igniting a gaseous fuel from a torch or a similar device. A piezoelectric element is housed in a plastic-like casing which simultaneously serves as an insulator and which is integrally connected with a U-shaped spring carrying an impact body for manually striking the piezoelectric element.
