    按钮开关

    按钮开关是什么?

    按钮开关是指利用按钮推动传动机构、使动触点与静触点接通或断开并实现电路换接的开关。

    按钮开关的工作原理

    • 按钮开关又称控制按钮(简称按钮),是一种手动且一般可以自动复位的低压电器。按钮开关通常用于电路中发出启动或停止指令,以控制电磁起动器、接触器、继电器等电器线圈电流的接通和断开。
    • 按钮开关是一种按下即动作,释放即复位的用来接通和分断小电流电路的电器。一般用于交直流电压440V以下,电流小于5A的控制电路中,一般不直接操纵主电路,也可以用于互联电路中。
    • 在按钮未按下时,动触头与上面的静触头是接通的,这对触头称为常闭触头。
    • 在按钮未按下时,动触头与下面的静触头是断开的,这对触头称为常开触头。
    • 按下按钮,常闭触头断开,常开触头闭合;松开按钮,在复位弹簧的作用下恢复原来的工作状态。

    按钮开关的类型

    按开关操作分类:

    • 瞬时型按钮开关:需要用户按住按钮才能引发相应操作,放开按钮后操作立即复位(断开)。
    • 闭锁型按钮开关:带有常开或常闭触点,开关保持在设置的触点状态,直到再次按下按钮即可切换状态。

    按使用场合的不同和具体的用途分类:

    • 根据使用场合选择按钮的种类,如开启式、防护式、防水式、防腐式等;
    • 根据用途选择用合适的形式,如手把旋转式、钥匙式、紧急式、带灯式等,例如控制台柜板面的一般按钮可先用开启式;如需要显示工作状态则用带指示灯式;在非常重要处,为防止无关人员误操作宜选用带钥匙式;在有腐蚀性气体处要用防腐式。

    按工作状态、批示和工作情况的要求选择按钮和指示灯的颜色:

    • 用于表示“启动”或“通电”的用绿色,表示“停止”的用红色。
    • 另外指示灯的电压(灯泡)分为3V、12V、24V等几种。

    按控制回路的需要,确定不同的按钮数:

    • 如单钮、双钮、三钮、多钮等。
    • 例如,需要“正”“反”“停”三种控制时,可用三只按钮,并装于同一按钮盒内;
    • 只需作“启动”及“停止”控制时,则用两只按钮组装在同一个按钮盒内。

    按钮开关的应用

    按钮开关在各种不同的应用中很受欢迎,包括计算器、按钮电话和许多家用电器。

    • 您可以在家庭、办公室和工业应用中找到它们。
    • 按钮开关可以打开和关闭机器,或使设备执行特定操作,例如电子计算器、笔记本电脑或台式机的电源按钮。
    • 在某些情况下,特别是对于商业和工业用途,按钮开关可以通过机械连杆连接,这意味着按下一个按钮可以导致另一个按钮释放。
