What do I need to pay attention to when using micro switches?

1) The micro switch is fixed.

For the main body, use a small screw of M2 to fix it on a smooth surface with the following torque. In addition, to prevent loosening of the screws, it is recommended to use washers at the same time.

2) In the case of hand soldering, use the electric temperature 320 with temperature adjustment to complete the work within 3 seconds, and be careful not to exert force on the terminal part during the operation.

3) When using with small currents and voltages, it is recommended to use a low-power circuit type (AU-clad contact).

Nothing to pay attention to! The left and right mouse buttons you are using are pressed (micro switches)! Except for not pushing too hard, there are no precautions! aqui te amo。

Many people may not have heard of the micro switch, let alone know what it is, in fact, in our lives, it is necessary to use it frequently, as long as it is an electronic device, it is inseparable. Let's find out todayMicroswitchesFirst, the principle of micro switch.

The mechanism of the micro switch is made of tiny contact spacing and fast action, in those equipment that need to be frequently replaced circuits, they are automatically controlled and safeguarded, usually widely used in electronic equipment, instrumentation, mining, power systems, household appliances, aerospace, missiles, tanks and many other fields, its principle is to pass the external mechanical force through the transmission of the elements, and then the force is used on the action reed, when the displacement of the action reed to a critical point, it will produce instantaneous action, At the end of the action reed, its moving contact and fixed contact can be quickly turned on or off, and the reverse action can be completed instantly.

2. What are the precautions for micro switches?

1. If it is the main body of the fixed switch, be sure to use a small screw of M2, and then put the small screw on the smooth surface to fix it with the following torque, and in order to prevent the screw from loosening, it is best to use a washer under the screw at the same time.

2. In the free state, it must be noted that the force cannot be directly applied to the button or exciter, but the force should be applied to the vertical direction corresponding to the button when it is used.

3. The action setting after the micro switch action should be more than 70% of the value as the standard, in the case of the switch opening, the action body can not be directly set in the position of the action limit, otherwise it is easy to open and close because of the impact, which will shorten its service life.

4. Even if the action characteristics of the micro switch jump up and down at 20% of the specification value, it will not cause failure due to changes.

5. In the case of welding, you must remember to use the electric temperature with temperature adjustment 320 max), and to complete the job within 3 seconds, be sure not to exert force on the terminal part during the process of completing the job.

6. If the micro switch is used under small current and voltage, it is recommended to use the low-power circuit type, not the high-power one.

I conclude: That's what I shared aboutMicroswitchesThe principle of the micro switch and what precautions are in place. Micro switches are mainly composed of five categories, so you must understand clearly before buying, if you still want to know more about decoration, please continue to pay attention to this**Oh!
