    • A thermal switch having a thermally, responsive bimetallic member that exhibits a snap-action response and a pair of relatively movable contacts positioned relative to the thermally responsive bimetallic member such that the thermally responsive bimetallic member is positioned to actuate one of the pair of relatively movable contacts by transitioning between one and another of the first and second stable states, the bimetallic member being a bimetallic material fabricated of two materials having different coefficients of thermal expansion and formed in a non-planar shape to achieve a snap-action between first and second stable states as a function of temperature and having an artifact formed as a localized heat-treated area in a surface of a first of the two materials and cooperating with the non-planar shape to achieve the snap-action.
    • 一种热开关,其具有表现出快速响应的热响应双金属构件和相对于热响应双金属构件定位的一对相对可移动的触点,使得热响应双金属构件被定位成致动所述一对相对可移动的 接触通过在第一和第二稳定状态中的一个和另一个之间转变,双金属构件是由具有不同热膨胀系数的两种材料制成的双金属材料,并且形成为非平面形状以实现第一和第二稳定状态之间的卡合动作 作为温度的函数的稳定状态,并且具有在两种材料中的第一种材料的表面中形成为局部热处理区域的伪像,并且与非平面形状配合以实现快速动作。
