The touch switch, also known as a button switch, first appeared in Japan. When using a four foot touch switch to meet the operating force conditions, pressure is applied to the switch for opening and closing functions. When the pressure is revoked, the four foot light touch switch will be closed, and the internal structure of the four foot light touch switch relies on metal shrapnel to protect the stress situation, achieving connection and disconnection. This is only one point of the four foot touch switch. If you want to know more information about the four foot touch switch, please continue to read!
The working principle of a four foot light touch switch is actually similar to the working principle of an ordinary button switch, consisting of a combination of normally open and normally closed contacts. In a four foot light touch switch, the normally open contact acts as a circuit when pressure is applied to the normally open contact; When this pressure is lifted, it returns to the original normally closed contact, also known as disconnection. The force of pressure is the action of using our hands to open and close buttons. In summary, the working principle of the four foot light touch switch is still easy to understand.
The four foot touch switch used under different conditions or environments may vary in specifications and models. This requires a considerable familiarity with the specifications and models of different series. The main specifications of four foot light touch switches include side plug-in, patch type, plug-in type, etc. In addition, there are 8 * 8 series waterproof light touch switches, 6 * 6 series waterproof light touch switches, 10 * 10 series waterproof light touch switches, and 12 * 12 series waterproof light touch switches. Different specifications of four foot light touch switches have different model numbers and series. For example, four foot light touch switches such as 6 * 6 * 5.5/12/10/13/3.3/17/21/26mm.
The scope of application of the four foot touch switch was also briefly mentioned before, including electric wind, microwave oven, television, electronic fat scale, Rice cooker and electronic kitchen scale in household appliances; Monitors, visual walkie talkies, etc. in security products; Recording pens, cameras, etc. in computers; Call system in medical equipment, Sphygmomanometer, thermometer, etc., Massage chair in fitness equipment, running meter, etc., in these fields, four foot touch switches are involved in applications. In addition, there are many aspects, and it can be seen from the application range of the four foot touch switch that this type of switch will be more widely used in future development.
The selection method of four foot light touch switch will directly affect the use of the product. So when selecting a four legged light touch switch, attention should be paid to its physical properties such as solderability, protection, and conductivity. The service life is long, and the touch is rough. These external surface factors will also determine the quality of the four legged light touch switch. In order to reduce resistance, silver plating will be used on the pins, so high-quality four pin touch switches need to be controlled in terms of silver plating thickness and process. The final silver plating is above 0.3um, thin silver is 0.2um, and 0.1um is white. Is the protection of the four foot light touch switch equipped with waterproof and dustproof functions after silver plating? Otherwise, even with good silver plating treatment, it will be oxidized by air!
Precautions for the use of four foot touch switches. Regarding the welding of the switch, it is necessary to confirm the production conditions. Due to different conditions, deformation and deterioration may also occur when applying on the terminals, so it is important to pay attention to this when using. For the thermal stress effect of four foot touch switches, sufficient confirmation preparation should be made before use; After the first welding process, please return to the normal temperature state before conducting the second welding. If heated continuously, it will change the appearance of the four foot light touch switch, and the terminals may also fall off, resulting in a decrease in electrical characteristics. The resistive load of the four foot light touch switch is pre designed, please pay attention to confirmation when using other loads.
