微动开关工作原理

2014-8-25 17:07:35点击:

外机械力通过传动元件(按销、按钮、杠杆、滚轮等)将力作用于动作簧片上,当动作簧片位移到临界点时产生瞬时动作,使动作簧片末端的动触点与定触点快速接通或断开。当传动元件上的作用力移去后,动作簧片产生反向动作力,当传动元件反向行程达到簧片的动作临界点后,瞬时完成反向动作。微动开关的触点间距小、动作行程短、按动力小、通断迅速。其动触点的动作速度与传动元件动作速度无关。

微动开关在需频繁换接电路的设备中进行自动控制及安全保护等,广泛应用在电子设备、仪器仪表、矿山、电力系统、家用电器、电器设备,以及航天、航空、舰船、导弹、坦克等军事领域,已经广泛应用于以上领域,开关虽小,但起着不可替代的作用。
