In a reed switch manufacturing machine the closed glass-sealing chamber is modified so that inert gas introduced during fusion of the glass envelope is directed onto the back of gold-plated reflectors in the chamber. This enhances the life of the reflectors resulting in an improved product quality and product yield.
