WIPO Patent Application WO/2011/115059
Kind Code:

Abstract:
In order to provide a contact switching device having excellent shock resistance, and which does not require skill to braze parts made from metal to the through hole in the ceramic sealed container, contacts are opened and closed by driving a contact mechanism disposed within a sealed space, according to the excitation and demagnetization of an electromagnet disposed outside the sealed space. In particular, a ceramic plate (131) which holds the fixed contact terminal (133) of the contact mechanism is bonded together with a first metal part to form a single body in the form of the sealed container, and the outer peripheral part of the gas exhaust pipe (134) is brazed thereto, with a metal ring part (172a), disposed along the periphery of the opening of the through hole (131b) provided to the ceramic plate (131), positioned therebetween.
