The high permeability of the ferromagnetic reeds in a reed relay causes a pronounced skin effect with increasing signal frequency. 干簧式继电器中铁磁簧片的高磁导率会随信号频率的增加而产生很强的趋肤效应。
Mercury wetted reed switches are constructed in the same way as dry reed switches with the addition of a small amount of mercury inside the glass tube. 水银湿簧开关与干簧继电器的构造方式相同，仅仅是在玻璃管内部增加了少量了的水银。
