Title:
THERMALLY REACTIVE SWITCH
Document Type and Number:
WIPO Patent Application WO/2008/018516
Kind Code:
A1
Abstract:
This invention provides a thermally reactive switch (1) comprising a hermetically
sealed vessel (2) comprising a metallic housing (3) and a lid plate (4), electroconductive
terminal pins (10A, 10B) fixed in a hermetically sealed state in the lid plate
(4), a fixed contact (8) fixed in the electroconductive terminal pin (10A), a
thermally reactive plate (6), one end of which is electroconductively connected
and fixed to the inner face of the hermetically sealed vessel (2) and undergoes
reversion of the inflection direction at a predetermined temperature, and a
movable contact (7) fixed to the other end of the thermally reactive plate (6).
The movable contact (7) and the fixed contact (8) comprise a silver-cadmium
oxide-base contact. A gas containing not less than 50% and not more than 95% of
helium is sealed within the hermetically sealed vessel (2) so that the pressure
is not less than 0.38 atm and not more than 0.68 atm at room temperature.
