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

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. c1 x6 G' X! ]8 ^8 C6 ~6 ]9 Y

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.3 r6 k) c; J$ T5 {' t& K$ J' G/ r+ Y
