Abstract

Official abstract text for this publication.

An object of the present invention is to provide a contact switching device that does not require proficiency for brazing a metal component to a through-hole of a sealed container made of ceramic, and is excellent in impact resistance. For this, there is provided a contact switching device that drives a contact mechanical portion arranged inside a sealed space to switch contacts, based on excitation and degauss of an electromagnet portion arranged outside the sealed space. Particularly, a ceramic plate ( 131 ) holding a fixed contact terminal ( 133 ) of the contact mechanical portion, and a first metal component are bonded and integrated to form the sealed space, and an outer circumferential portion of a vent pipe ( 134 ) is brazed through a metal ring portion ( 172 a ) arranged along an opening edge portion of a through-hole ( 131 b ) provided in the ceramic plate ( 131 ).
