以下就拿60335-1 来说

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).! K4 X. |' Q* ]

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.

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; j G1 e' m0 s; h( Y
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.! \# p7 I; c- J7 F

判断是不是温控器是要运行产品来判断的9 W' Q) J# x9 n, x2 `8 T

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.5 ]' t: z% t: z4 W! W

另外希望管理员给出加威望和金币的原则. |
