邰康轰2014单片机最小系统 自锁开关与电源指示灯怎么接 -
解虞卢13262882987 ______ 你是想用自锁开关做单片机最小系统的电源开关吧?如果是的话,直流电源的负极和单片机最小系统的负极相连,正极接到自锁开关的常开触点A端,单片机最小系统的电源正极接到自锁开关B端.电源指示灯用3毫米直径的红色LED,,LED的正极接单片机的正极,LED的负极接1/4W200欧姆的电阻,电阻的另一端接单片机的负极,即可.

解虞卢13262882987 ______ 这是个三路开关,你可用其中的两对即可,下面三个脚各自对应上面的三个脚.
邰康轰2014按钮开关二处控制怎样接线? -
解虞卢13262882987 ______ 按钮开关二处控制怎样接线?按钮开关接线图解析一这张按钮开关接线图,看起来是漏电断容器接入接触器,在接入热继电器;漏电断容器的另一端接入热继电器,热继电器和接触器、启动停止按钮相接入,构成成为一个电路的回路.按钮开关接线图解析二这张按钮开关效果接线图相比于上一张,更容易简单理解并且掌握.只需要接触器、空气开关、断路器、停止和开启按钮.根据线条的走向,可以大概看出整个按钮开关接入电路的一个状态,以及电流和电压以及回路的构成.其实要接入电路中,中间的使用的线也是极其有讲究的.如果按钮上有五个接线柱,其中两个就应该是端子接灯,另外则是开关的,区分两种接线口,把相同的接口串结一处,就行了.
邰康轰2014380V的交流接触器加两个按钮开关怎么自锁! -
解虞卢13262882987 ______ 自锁的方法是把接触器自锁触点,,接在启动按钮的两端,自锁是常开触点,接触器的吸合,自锁闭合,使启动按钮始终保持在导通状态. 交流接触器(Alternating Current Contactor)广泛用作电力的开断和控制电路. 从用途来角度,交流接...
