按钮开关实际上是需要人们手动去发出各种信号来控制电路或设备的一种装置，它主要就是通过按钮推动传动机构达到让动静触电的接通和断开的开关，一般基本的启动、停止、变速等等都能通过它来控制。

　　The button switch is a device that requires people to send out various signals to control the circuit or equipment manually. It is mainly a switch that can make the dynamic and static electric shock on and off by pushing the transmission mechanism through the button. The general basic start, stop, speed change and so on can be controlled through it.

　　一个按钮开关是有两对触电的，每对则是由一个常开和常闭触电组成，按下的时候两对触电会同时发出动作，常闭触点断开，常开触点闭合。

　　A button switch has two pairs of electric shock, each pair is composed of a normally open and a normally closed electric shock. When pressed down, the two pairs of electric shock will send out actions at the same time, and the normally closed contacts will be opened and the normally open contacts will be closed.

　　如何正确的使用按钮开关？

　　How to use the button switch correctly?

　　首先要知道它的具体应用，一般是在各种电气自动控制电路，人们手动发出控制信号就能控制各种接触器、继电器、电磁启动器等装置，大家在选择的时候必须要根据使用的环境场合等来决定。

　　First of all, we should know its specific application, which is generally in various electrical automatic control circuits. People can control all kinds of contactors, relays, electromagnetic starters and other devices manually by sending control signals. When we choose, we must decide according to the environment and occasions.

　　按钮开关种类也是有很多的，如果需要选购，必须要先明确它的使用环境和用途，比如有嵌装在操作面板上的，这种可以选择开启式，有的需要用来显示设备的工作状态，那就需要选光标式的，还有的场合是很容易出现误操作的，这种情况就适合选用钥匙操作式的按钮开关。

　　There are many kinds of button switches. If you need to buy them, you must first clarify their use environment and use. For example, if there are embedded in the operation panel, you can choose the open type. Some need to display the working state of the equipment, then you need to select the cursor type. In other cases, it is easy to misoperate. This situation is suitable for the key operation type Button switch.

　　根据不同回路的要求，按钮开关还需要确定需要按钮开关的数量，常见的有单联钮、双联钮和三联钮等。

　　According to the requirements of different circuits, the number of button switches needs to be determined. The common ones are single button, double button and triple button.

　　需要注意的是，按钮开关的安装和使用都必须要保证安全可靠，也就是在安装的时候必须反复检查是否牢固，接线是否可靠，如果按钮开关需要放置在高温场合，那很容易发生变形导致松动，这种情况下要在接线螺钉上加套绝缘塑料管来防止造成短路的情况。

　　It should be noted that the installation and use of the button switch must ensure safety and reliability, that is, during the installation, it must repeatedly check whether it is firm and whether the wiring is reliable. If the button switch needs to be placed in a high temperature situation, it is easy to deform and cause looseness. In this case, an insulating plastic pipe should be set on the wiring screw to prevent short circuit.
