Abstract

A glass-metal leadthrough that is useful, for example, for an ignition device of an airbag. The glass-metal leadthrough has two parallel metal pins sealed in a glass stopper on a part of their length, so that they project outwardly from both sides of the stopper beyond its front sides. A cover piece is disposed on one of the front sides and provides a metal contact between one of the pins and a metal sleeve that surrounds the glass stopper.
