The signal contact includes a first portion and a second portion.
激励电极位于信号触点的第一和第二部分之间。
The actuation electrode is positioned between the first and second portions of the signal contact.
作为技术指标，如果在最大信号电平下采用冷切换而非热切换，那么触点寿命将会从105次开关次数延长至108次开关次数。
As the specifications state, if cold switching is used instead of hot switching at maximum signal levels, contact life is extended from 105 closures to 108 closures.
