只有正确的安装按钮开关才能保证其正常工作，那么在按钮开关安装的过程中有哪些注意事项？

　　Only the correct installation of the button switch can ensure its normal operation, so what are the precautions in the process of button switch installation?

　　1.按钮安装在面板上时，应布置整齐，排列合理，如根据电动机启动的先后次序，从上到下或从左到右排列布置。相邻按钮间距为50~ 100mm。

　　1. When the buttons are installed on the panel, they should be arranged orderly and arranged reasonably. For example, according to the sequence of motor starting, they should be arranged from top to bottom or from left to right. The distance between adjacent buttons is 50 ~ 100 mm.

　　2．同一设备部件的几种不同的工作状态（如上、下，前、后，左、右，松、紧等）应使每一对相反状态的按钮安装在一组。应用红色按钮表示停止，绿色或黑色表示启动或通电，不要搞错。

　　2. For several different working states of the same equipment component (as above, below, front and rear, left, right, loose, tight, etc.), each pair of buttons in opposite state shall be installed in a group. Apply red button to stop, green or black to start or power on. Don't make a mistake.

　　3.为了应付紧急情况，当面板上按钮较多时，总停按钮应安装在显眼而容易操作的地方，最好采用红色蘑菇头按钮或做明显的标记。

　　3. In order to deal with emergency, when there are many buttons on the panel, the main stop button should be installed in a conspicuous and easy to operate place. It is better to use red mushroom head button or make obvious marks.

　　4.由于按钮触头间距离较小，如有油污等容易发生短路故障，因此应保持触头的清洁。

　　4. Due to the small distance between the contacts of the button, if there is oil pollution, it is easy to cause short circuit fault, so the contact should be kept clean.

　　5.安装按钮的按钮板和按钮盒必须是金属的，并设法使它们与机床总接地母线相连接，对于悬挂式按钮必须设有专用接地线，不得借用金属管作为地线。

　　5. The button board and button box for installing buttons must be metal, and try to connect them with the general grounding bus of the machine tool. For hanging buttons, special grounding wire must be set, and metal tube is not allowed to be used as ground wire.

　　6．按钮用于高温场合时，易使塑料变形老化而导致松动，引起接线螺钉间相碰短路，可在接线螺钉处加套绝缘塑料管来防止短路。

　　6. When the button is used in high temperature situation, it is easy to make the plastic deformation and aging, resulting in loosening, causing the short circuit between the connecting screws. An insulating plastic pipe can be added at the connection screw to prevent short circuit.

　　7．带指示灯的按钮因灯泡发热，长期使用易使塑料灯罩变形，应降低灯泡电压，延长使用寿命。

　　7. The button with indicator light is easy to deform the plastic lampshade due to the bulb heating, so the bulb voltage should be reduced to prolong the service life.

　　8．“停止”按钮必须是红色；“急停”按钮必须是红色蘑菇头式；“启动”按钮必须有防护挡圈，防护挡圈应高于按钮头，以防意外触动使电气设备误动作。

　　8. "Stop" button must be red; "emergency stop" button must be red mushroom head type; "start" button must be equipped with protective ring, which should be higher than the button head, so as to prevent accidental touch and misoperation of electrical equipment。
