Abstract
An object of the present invention is to provide a contact switching device having high dimension accuracy and an inexpensive price, and including a small sealed space. For this, there is provided a contact switching device that drives a contact mechanical portion () arranged inside a sealed space () to perform contact switching, based on excitation and degauss of an electromagnet portion () arranged outside the sealed space (). Particularly, a ceramic plate () holding a fixed contact terminal () of the contact mechanical portion () is bonded to and integrated with an upper opening edge portion of a metal cylindrical flange (), while a plate-like yoke () is bonded to and integrated with a lower opening edge portion opposed to the upper opening edge portion to form the sealed space ().
