开关可以有不同的结构，可以有两个断开接点也可以有1个断开接点和1个闭合接点。
The switches are available in several configurations, with 2 normally open contacts, or 1 normally open and 1 normally close contact.
触接点的开启与闭合产生感应电压。
Opening and closing of the contact points creates induced voltage.
塞贝克电势的产生与大小，取决于构成闭合回路的导体及接点温度。
The generation of Seebeek potential and its value depends on the conductors comprising the close loop and the temperature at the contact point.
