Claims

[Claims for Utility Model Registration] (1) A switch body having a communication hole for the refrigerant in the cooling cycle and having an internal chamber communicating with the communication hole, and two diaphragms provided in the internal chamber. a diaphragm part whose peripheral edge is welded so as to have a cavity part, and a thin tube which is attached to the cavity part through an opening part at one end, has a closed end part at the other end, protrudes from the communication hole, and has a refrigerant sealed inside. , a fixing member that fixes the thin tube to the communication hole, has a passage around the communication hole communicating with the internal chamber, and is fixed to one diaphragm of the diaphragm part;
a tip-shaped insulating slider with one end facing the other diaphragm and having a magnet on the inner periphery; a cylindrical non-magnetic guide provided on the outer periphery of the slider in the internal chamber; A resin cover has two terminals attached by caulking and is placed to cover the guide, and between this cover and the slider, one abuts the inner surface of the cover and the other protrudes into the slider. At the same time, a mold member is provided with a built-in reed switch that connects each lead wire to each of the terminals, and the mold member is sandwiched together with a seal member between the cover and the guide and surrounds and supports the protruding portion of the mold member into the slider. A super heat switch comprising a shielding member made of a non-magnetic material and a spring inserted between the shielding member and the slider. (2) A utility model registration claim comprising: a screw screwed into the cover, one end of which abuts against one of the molded members; and a leaf spring inserted between the shielding member and the other molded member. 1
Super heat switch as described in section. (3) The super heat switch according to claim 1, which is a utility model, and comprises a terminal and a lead wire of the reed switch connected by a flexible conductive member. (4) The super heat switch according to claim 1, wherein the terminal and the lead wire of the reed switch are connected by a slidable conductive member.
