脚踏开关是一种通过脚踩或踏来控制电路通断的开关,使用在双手不能触及的控制电路中以代替双手达到操作的目的。
脚踏开关在医疗器械、冲压设备、焊接设备、纺织设备、印刷机械中应用广泛。
在电子行业中的应用,如小金刚,端子机的配置中,有自动,和寸动,寸动就是应用脚踏开关。踩一下,一段行程。

简单的脚踏开关其实就是内置一个行程开关,当脚踏给予信号的时候,开关执行。但是现在焊接领域脚踏开关的功能还担当控制输出电流大小的作用。这种类型的脚踏开关还可以分为两类:一、机械式脚踏开关;二、感应式脚踏开关。机械式脚踏开关是传统的齿轮齿条传动,感应式是通过电磁感应等原理。

选用脚踏开关应注意以下几点:

1.根据负载的性质和电流值的不同,请注意产品的额定负载。
2.搬运以及移动时请注意内部配线的短路、断路等现象发生。
3.使用在有大量水、油、粉尘等场所时请注意产品的防护等级。
4.重压和冲击是造成产品损坏的直接原因,使用时请务必小心。
