Rotary switch dials,push switch knob,Adjustable control knob

Now, the push switch knob is widely used as the adjustment mode of equipment in many fields. In our daily life, this type of switch is also used more frequently. However, few people know the working principle and characteristics of knob adjustment. The following is a detailed introduction to the design and advantages of this switch according to its design concept and use skills.

At present, the Adjustable control knob switches are mainly divided into two types. One type is that the contact piece touches the start key first, and then the contact piece completely disengages from the start key, and then contacts the close key. Another design method is to make the contact piece touch both contact points, but the final effect is controlled by the contact area. These two types are widely used in many fields, and each has its own advantages. In the eyes of many people, the switch in the first mode is more safe and reliable, and the switch in the second mode may have certain safety risks.

However, after years of scientific research and practical experience, both types of switches can well ensure the normal operation of relevant equipment and have good safety performance. Therefore, when choosing to install the rotary switch, the designer needs to install more suitable switch types according to the use of the equipment.

In addition, as the switch is a frequently used part, in order to prolong the service life of this switch and ensure the working efficiency of relevant mechanical products, the basic raw materials of the rotary switch dials are made of metal. Compared with other switches, metal switches are more comfortable to use, faster to respond to work, and better to switch the equipment between on and off.

In recent years, due to the continuous upgrading of various electrical products, many parts also need to improve the sense of quality. Therefore, many knob switches have adopted new technologies and production processes. What surprises the public most is that the knob switch breaks through the traditional two gear mode and adds other adjustment functions between on and off. For example, in the electric fan, the speed of the fan is divided into first gear, second gear and third gear. Such a random switching mode is to use the basic design principle of the rotary switch to increase the contact points, so as to successfully increase the gear.

After we clearly understand the working principle and characteristics of the knob switch, we can better feel the convenience it brings in our daily use, and better protect and repair this switch. After all, this switch directly determines whether the equipment can operate normally, and also directly determines the service life of the machine.

What are the installation procedures for the rotary switch?

1. open the button cover screwdriver and remove the nut;

1. insert the lower part of the open switch into the plate hole;

1. screw on the nut and insert the button cover;

In addition, the Adjustable control knob switch has no positive and negative poles. There is only a positive pole on the circuit board. The negative pole is the common part on the board. However, the button switch has a normally open contact, that is, there is a side over there. Just connect it! There is usually a snap ring in the inner hole of the knob. Just align the inner hole of the knob with the knob rod to press it. Pay attention to check whether the snap ring is still there. If the snap ring is lost, the knob will be loose.
