What problems should we pay attention to when purchasing the light touch switch? We will give you detailed details here.
When it comes to touch switch, many people think of switch directly. In fact, there is still a big gap between touch switch and switch. Of course, there are some similarities. Touch switch is an electronic component, which needs to be combined with some products to play a role. Most of them are assembled in it. Generally, they are invisible. The switch usually means that we can see everywhere in our daily life, and most of them are still touchable. We can also understand that the touch switch is a special switch in the switch.
Switches can generally be divided into double-controlled switch, midway switch and multi-switch, which can be explained as follows:
Multi-switch: Multi-switch mainly refers to the buttons on the panel. If there are several buttons, it is called several switches. In addition, each button can be controlled by three.
Midway switch: also known as multi-control switch, each button has six or four terminals behind it. The midway switch can achieve N (N greater than 2) switches to control a lamp together.
Double-control switch: It is divided according to the control mode, and there are also single-control switch and multi-control switch, in which single-control is the most used one. Dual-control switch can realize two switches to control a lamp together, of course, it can also realize all the functions that single-control switch can achieve.
The above is to say that the switch is mentioned in passing when touching the switch. The following is the main topic. The purchase and selection of the switch has always been the concern of many people. So today, the editor of Precision Dragon Technology Co., Ltd. will share with you five points of knowledge that should be remembered when purchasing the switch:
First, strict factory inspection is also an indispensable element of quality. For example, hand feel, appearance, resistance and other items are spot checks or full checks. These seemingly minute details determine its quality.
Secondly, the concave and convex of the production process also determines the quality. The production process depends on the cooperation of the management ability of the producer Best Electronics, staff quality awareness and quality assurance ability.
Third, life and feel are determined by the shrapnel and stroke of the light touch switch. Short journey and low noise will increase their life, and vice versa.
Fourthly, the reliability of the touch switch can be said to be determined by the structure of the touch point. The larger the touch surface of the touch point, the better, and vice versa.
Fifth, in order to reduce the touch resistance, the light touch switch can be used. The lead of the light touch switch is usually made of brass or phosphorus copper, which is basically treated by silver plating. This directly affects the welding and touch resistance of the switch, so we should pay more attention to the selection.
