    • A temperature limiter includes a switch head with a switching contact and a temperature sensor having elongate expansion elements of different thermal expansion coefficients. The expansion elements are fixed relative to one another in one end zone and movable relative to one another in the other end zone. Slidably supported in the switch head is a ram which abuts against the movable expansion element and has an end portion constructed to allow application of welding or soldering. A switch sleeve is placed over the ram end portion and adapted to actuate the contact. The switch sleeve is movable relative to the ram during a calibration phase, until reaching a position which is determinative for calibrating a desired response temperature of the switching contact. In this position, the switch sleeve is then securely fixed to the end portion by fusion welding or soldering.
    • 温度限制器包括具有开关触点的开关头和具有不同热膨胀系数的细长膨胀元件的温度传感器。 膨胀元件在一个端部区域中相对于彼此固定,并且在另一个端部区域中可相对于彼此移动。 在开关头中可滑动地支撑着一个抵靠活动膨胀元件的冲头,并具有构造成允许施加焊接或焊接的端部。 开关套筒放置在柱塞端部上方并且适于致动接触件。 开关套筒在校准阶段期间相对于压头可移动,直到达到用于校准开关触点的期望响应温度的决定性的位置。 在这个位置,开关套筒然后通过熔焊或焊接牢固地固定到端部。
