是指在产品正常工作时动作用于控制温度的. 比如98度断开,60度闭合.  (饮水机的温控器)

也是指在产品正常工作时动作用于控制温度的, 但是如果温度在98度断开后,是不会闭合的,比如电热水壶,谁烧开之后是不会反复烧的

这个主要是指在非正常动作的, 又可以分为自复位(self-resetting 和和非自复位的(non-self-resetting).

在这里要指出的是光从外观是看不出这个元器件是thermostat 还是 self-resetting thermal cutout的. / m4 G5 j* a9 A( P" I6 W' o8 w

所以6楼中第一章图片是用在冰箱中的温控器,一般情况下是对的 i9 n( l) m& K! |
但是第三张图片绝对不能说是thermal cutout. 也许用在A产品中是thermal cutout但是用在B产品中就是thermostat了. 举个例子,sandwich maker(三明治炉)中很多温控器都是这个样子的.

60335-1 的A2已经修改了,所以thermal link 不一定要有证书的.
