[Detailed description of the invention] [@Ming's technical field] Taibou decoy H'11-)-' 2 Itsu Imada Kyoto V group A
[Technical Background of the Invention and Problems Therewith] A reed switch is a switch in which a reed member is sealed in a glass tube and an inert gas is introduced into the glass tube so that the reed switch is not affected by the external atmosphere. This switch performs opening and closing operations using a magnetic field outside the glass tube. A switch that opens when an external magnetic field is present is called a self-holding switch, and a switch that closes when an external magnetic field is present is called a non-self-holding switch. The present invention relates to a non-self-holding switch.

On the other hand, recently there has been a particular demand for materials for lead members that have low electrical resistance as well as good sealing properties with glass. This is because lead members that generate less heat are required as devices become more powerful. If the amount of heat generated is large, it can cause problems such as damage to the reed switch itself and damage to peripheral equipment.
