  • Sealed contact device, a method of producing a sealed contact device, and a sealing method
    Patent number: 6204460
    Abstract: A configuration for forming a gastight space is prevented from being projected from a housing, so that a projection is not formed on the housing. A sealed contact device includes a housing including a container body having an open end portion, the container body being made of ceramic, a metal lid connected to the open end portion to form a gastight space, a stationary contact and a movable contact disposed in the container body, and a sealed vent portion formed in the metal lid, in which the sealed vent portion is formed by sealing a vent hole formed in the metal lid after exhausting a gas in the gastight space and supplying a desired gas into the gastight space, via the vent hole.
