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4 A! b, W1 M, J% x; l0 o/ p1 a5 B: m

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.! |3 T! b- O% [8 Q. B4 h

判断是不是温控器是要运行产品来判断的) |2 v0 D* c/ I3 P, ]/ |

另外, 2楼的解释也有问题,前看下面的条款
+ j* c7 ]! g* L. L3 e24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not$ c. m* o0 Y% p! ~' v

Clause 19.& v# ~7 D% X( l' |/ h( M
60335-1 的A2已经修改了,所以thermal link 不一定要有证书的.

6 Q8 W2 U0 M+ w4 Y' J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.8 U6 w3 k) [( i: V: M& J. [9 S
