Claims

[Scope of claim for utility model registration] A sealed container forming an airtight space, a fixed electrode having a fixed contact at the tip of a fixed shaft fixed in the sealed container, and a fixed electrode that can be freely inserted into an insertion hole of the sealed container. A movable electrode having a movable contact disposed at the tip of a movable shaft that is moved toward and away from the fixed contact, a cylinder fixed to a sealed container and into which the movable electrode is inserted, and a movable electrode protruding from the cylinder. Spring means provided for spring-biasing the movable electrode in a direction away from the fixed electrode, the spring means integrally comprising a defining portion that defines a maximum displacement position of the movable electrode in the direction away from the fixed electrode. A sealed contact device comprising:
