Warm congratulations to my company website revision online！

Our factory is the product into the brand of high-quality electronic switch and socket direct manufacturers, switch products are: touch switch, toggle switch, straight key switch, blade switch, swing switch, micro switch; Socket products are: AC socket (in line,SMT), DC socket (in line,SMT), headphone socket (in line,SMT), USB. Products in line with the European Union "RoHS" standard of professional manufacturers, in order to ensure that can pass the "RoHS", our factory has purchased XRF spectrum detector (environmental protection test and electroplating thickness test). With the company's global business volume continues to expand, the original company's website style and content has far from meet the needs of customer experience, in order to show the majority of new and old customers step by step my company's scale and strength, understand the company's products and service content. The company decided to redesign the website and increase the publicity of the network.

Test and heat dissipation of sliding switch

Sliding switch life test No-load: The operator performs 100,000 no-load tests at a frequency of 60 times per minute. Requirements: (1) Contact resistance shall not exceed 200mΩ (2) Other, satisfied with mechanical, electrical performance. Sliding switch heat resistance test The test was conducted at 85±2℃ for 96 hours, and then at normal room temperature for 1 hour. Requirements: The appearance of permanent, to meet the mechanical, electrical performance. Sliding switch cold resistance test Place at 40±2℃. After 96 hours in an environment with relative humidity ranging from 90 to 96 degrees, the sample was placed in a normal environment for 1 hour for testing. Requirements: No abnormal appearance, meet the mechanical, electrical performance. Sliding switch wet test Place at 40±2℃. After 96 hours in an environment with relative humidity ranging from 90 to 96 degrees, the sample was placed in a normal environment for 1 hour for testing. Requirements: No abnormal appearance, meet the mechanical, electrical performance. With the development of fan manufacturing technology, the working stability and service life of fans have made great progress, and the average fail-free time is 50,000 hours. The use of fan heat can be reduced after the heavy radiator, so that the volume and weight of the rectifier is greatly improved, the cost of raw materials is also greatly reduced. With the increase of market competition and the decline of market price, this technology has become a major trend.

Toggle switch current magnitude test method and performance

Toggle switch this measurement method has the advantage of more intuitive, convenient. The disadvantage is that the current passing through the switch is very small when measuring, which can not destroy the oxide film on the contact surface, thus causing a large recognition error (larger). Therefore, this method is not recommended in the circuit resistance measurement of high voltage switch. Voltage drop method (voltammetry) indirect measurement: voltage drop method is the value of the DC current through the switch socket, with the millivolt meter measurement toggle switch socket in and out of the line between the voltage drop (mV), and then calculate the main circuit resistance of the switch socket with Ohm's law. Measurement lines using transformers and silicon rectifiers. At the same time, when the voltage drop method is used to measure the resistance of the main circuit, because the current through the sample is large enough to destroy the metal oxide film on the contact surface, reducing the measurement error, the measured value is more accurate, so the voltage drop method is recommended for the measurement of the main circuit of the toggle switch socket.   Toggle switch has a small contact interval and fast moving mechanism, with a specified stroke and a specified force for switching action contact structure, covered by the shell, the external drive rod of one kind of switch. Impact resistance: Impact durability means that the micro switch will not be damaged by the mechanical impact during transportation or installation, and it can meet the impact within the range of action characteristics. Misoperation impact refers to the impact range that the contact closed by impact during the use of micro switch does not separate within the specified time.
