    • A spring powered switching mechanism (100) in which the energy required to complete switching is stored in a spring (or springs) (3, 4) which are constrained in a "cocked" or stressed condition by a fuse wire (2). The fuse wire has the characteristic of having a relatively flat coefficient of resistivity over a large temperature range. The mechanism is operative to close (or open) electrical circuits permanently upon receipt of the appropriate electrical signal to the "fuse" or "bridge" wire which is caused to break as a result of the receipt of the electrical signal.
    • 一种弹簧供电的切换机构(100),其中完成切换所需的能量被储存在由熔断丝(2)限制在“起翘”或应力状态的弹簧(或弹簧)(3,4)中。 保险丝线具有在大的温度范围内具有相对平坦的电阻系数的特性。 该机构在接收到由于接收到电信号而导致断开的“熔丝”或“桥”电线的适当电信号时,可以永久地关闭(或打开)电路。
