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.

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.! w! I8 H+ C8 X9 U w! l2 c( E* R

判断是不是温控器是要运行产品来判断的- p4 E4 S @& e0 \! Q# n3 O8 B

. ^0 X6 v9 f# H4 s60335-1 的A2已经修改了,所以thermal link 不一定要有证书的.% f' d: i* f* M" U

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.
