ABSTRACT:
The reeds of a reed switch include convex portions embedded in a glass tube and extending into a cavity defined in the glass tube. The fulcrums about which the reeds are spring-operated are regulated by the positions of the convex portions, rather than by the interface position with the glass tube. As such, a reed switch having desired characteristics can be reliably fabricated regardless of manufacturing process variations.
