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)

如果分不清楚就按照说明书把产品运行一下,看一下就知道了究竟是什么了,然后再去查元器件的证书看看耐久的次数是不是符合要求) M/ m& h+ g# X9 U; ~ s3 ^
% {' D$ K7 i# @- U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.

# p" s, {5 F% o* g# ~, c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* Q6 z7 \, m; j+ w. }7 C
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.

另外, 2楼的解释也有问题,前看下面的条款# Q, u) D1 v) y) Z7 {
24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not

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

另外,我不知道什么人可以给别人加威望,如果只是版主可以的话,请确认是正确的说法后才加威望,否者很容易误导别人的.我不觉得贴了三个图片就可以加5个威望.且不说其中的说法有歧义.
