Toggle switch is a very common electrical component, which is useful in many electrical facilities. This kind of switch will affect the safety of electrical appliances, so the selection is very important. When selecting the toggle switch, pay attention to the selection of materials, not to choose from the shape alone. The specific selection methods are described in detail below.
Precautions when selecting the material of toggle switch:
1、 Material
Toggle switch material: including iron case, electronics, copper tape, bead, slingshot, etc.
The materials used in the toggle switch are excellent in terms of fire resistance, insulation, impact resistance and moisture resistance. The materials are stable and not easy to change color. In addition to the high-grade plastic, the current switch panel also has gold-plated, stainless steel, copper and other metal materials, providing more and more choices for people.
2、 Surface treatment
The surface is smooth and smooth, with even color and texture. Generally, it is a good product. The brand mark on the panel should be clear and full, and there should be no burr on the surface of the toggle switch.
3、 Choice of copper strip
1. The thickness of copper strip can improve the current passing capacity and reduce the resistance of copper piece itself;
2. Strong toughness, especially for the socket part of toggle switch, which is not easy to deform. Even if it is used for a long time, it can maintain the proper clamping force, ensure the close connection between the socket and the plug, and reduce the arc;
3. Anti oxidation, no rusting, reduce the resistance increase and heating problems caused by rusting;
4. Less riveting, preferably one piece of copper as a whole, further reducing the fracture of riveting part and the heating of rivets.
Toggle switch is a kind of electronic switch, which belongs to the category of electronic components. This kind of switch first appeared in Japan. The toggle switch is called sensitive switch. The main type of toggle switch mainly refers to the light touch toggle switch, which is often referred to as the light touch switch. The working principle of the toggle switch depends on the change of the force on the metal spring in its internal structure to realize the on-off of the switch, When using, we apply pressure to the operation direction of the switch to make the switch function close and turn on. When we want to turn off the switch, we only need to cancel the pressure. The toggle switch is mainly composed of five parts: insert, base, shrapnel, button and cover plate.
There are many types of toggle switches, mainly divided into two categories:
The first type is to use the metal reed as the contact piece of the switch. The contact resistance of the switch is small and the toggle switch has a good handle.
The second type is to use conductive rubber as the contact path. The contact resistance of this switch is small. When we select the switch, we cannot blindly follow the trend. We need to choose the appropriate switch according to our actual situation.
There are many advantages of toggle switch, such as small contact resistance, precise operation error, diversified specifications, etc., so its application range is also very wide, mainly used in electronic equipment and white household appliances, such as: audio-visual products, digital products, remote control, communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, testing Money pen, laser pen button and so on.
