以下就拿60335-1 来说

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5 _+ G+ P/ Y8 |; H# S; s

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).

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. V8 Z4 a0 G) o! y2 Z+ d1 e, g

- @5 J4 ^$ E/ q* a2 p4 F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.

- V2 h. W( F, d6 f60335-1 的A2已经修改了,所以thermal link 不一定要有证书的.1 R& y: {' e! ~8 b7 K% k

另外希望管理员给出加威望和金币的原则. |
