Title:
CONTACT SWITCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/115052
Kind Code:
A1
Abstract:
In order to provide a contact switching device with a high degree of dimensional accuracy, and which is also inexpensive and is provided with a compact sealed chamber, a contact mechanism (30) disposed within a sealed chamber (43) is driven in accordance with the excitation and demagnetization of a magnet (50) positioned outside the sealed chamber (43), thereby switching the contact. More specifically, a ceramic plate (31) holding a fixed contact terminal (33) of the contact mechanism (30) is integrated by bonding with the upper opening edge of a metal tubular flange (32), and a plate-shaped yoke (37) is integrated by bonding to the lower opening edge that faces the aforementioned upper opening edge, thereby forming the sealed chamber (43).
