U.S. stocks had another volatile session on Wednesday. The U.S. consumer price index, also known as CPI, rose at a slower pace in April than in the previous month, prompting some investors to hunt for bargains and pushing the three major indexes in New York to intraday highs in early trading. However, the market remained concerned about the prospect of an aggressive rate hike by the Fed, and the three major stock indexes turned lower in the afternoon before closing down. The Nasdaq fell more than 3% amid a broad sell-off in technology stocks. At the close, the Dow was down 1.02%, the S&P 500 was down 1.65% and the NASDAQ was down 3.18%.
Us CPI rose 8.3% year-on-year in April, higher than expected
Wednesday's data showed the CONSUMER price index rose 8.3% in April from a year earlier, down from 8.5% a month earlier but beating economists' consensus forecast of 8.1%. In addition, the sequential growth rate of April CPI and the year-on-year and sequential growth rate of April core CPI also exceeded market expectations. Analysts noted that the latest data showed that the inflation pressure has now spread to the US household goods, real estate, cars and other areas of consumers' daily life. After the figures were released, President Joe Biden bluntly called inflation unacceptably high.
All three major European stock markets rose on The 11th
In Europe, a slew of better-than-expected corporate earnings on Wednesday generally boosted markets, with all three major European markets ending the day higher. At the close, the U.K. was up 1.44 per cent, France was up 2.50 per cent and Germany was up 2.17 per cent.
International oil prices surged on The 11th, and U.S. oil rose nearly 6%
International oil prices rose sharply Wednesday. By the close, Nymex light crude for June delivery was at $105.71 a barrel, up 5.96%. London Brent crude for July delivery closed 4.93% higher at $107.51 a barrel.
Market Analysis of temperature control switch
Industry competition and marketization degree: relay industry development is more mature, the market competition is more sufficient, major producing countries including China, the United States, Japan, Germany, etc., including the United States, Japan, Germany enterprise occupies most of the high-end relay market share, is mainly used in industrial automation control, automotive, communications, aerospace and other fields. The output of relays of Chinese enterprises accounts for about half of the global output of relays, but they are mainly medium and low-end products, which are mainly used in household appliances, electricity, automobiles and other fields.
Basic principles and classification of temperature control switch
Basic concept and principle of relay: relay is a control component that automatically disconnects when the input parameters (such as electricity, magnetism, light, heat, sound and so on) in the circuit reach a specified value, which can make the output parameters of the circuit change in a predetermined step. In circuits, relays mainly control, protect, regulate and transmit information. The relay has an induction mechanism that reflects external input parameters, an executive mechanism that realizes "on" and "off" control of the controlled circuit, and an intermediate comparison mechanism that compares, judges and converts the size of the input.
As a control element, relays have the following functions:
(1) Expand the control range, such as multi-contact relay control signal reaches a certain value, according to the different forms of the contact group, at the same time open and close the multi-circuit;
(2) amplification, such as sensitive relay, intermediate relay, etc., with a very small amount of control, can control a large power circuit;
(3) comprehensive signals, such as when multiple control signals are input into the multi-winding relay in a specified form, after comparison and synthesis, to achieve the predetermined control effect;
(4) Automatic, remote control, monitoring, such as the relay on the automatic device and other electrical appliances together, can form a program control circuit, so as to realize automatic operation.
In the competition of the temperature control switch market, enterprises in the United States, Japan and other developed countries constantly consolidate their dominant position in the global market by establishing technical standards, controlling core technologies, strengthening the integration of industrial chains, and firmly mastering the dominance of technical standards and international rules. In recent years, in order to further strengthen the core competitiveness, enterprises in the United States, Japan and other developed countries continue to expand temperature control switch products and speed up technology integration. Their business scope has broken through simple relay manufacturing and developed to industrial control, system integration and other fields. The key to the competition in the high-end field has developed from the competition of quantity to the competition of the basic research and development of new relays, key materials, special equipment and other core products.
The raw material of the temperature control switch
The temperature control switch cost of relay is mainly determined by raw materials, which are mainly iron, silver, copper and other metals, accounting for about 74.4% of the production cost, labour and manufacturing costs accounting for 13.7% and 11.9% respectively, silver, copper and iron materials accounting for 36%, 21% and 7% of the raw material cost respectively. The price of three raw materials has a certain impact on the profitability of the whole industry. In addition to the main metal raw materials of the temperature control switch, engineering plastics and enamelled wire are also important components of relays, and the overall supply of raw materials is stable at present.
The application domain of the temperature control switch
The rapid development of temperature control switch emerging relays. The application field of relays has changed from traditional application fields, such as household appliances and power automation control equipment, ships and new energy. Relay products have been transformed from low-end products to high-end products, such as high-voltage DC relay, high-performance industrial control relay, low-power energy-saving relay, new-generation communication relay, high-frequency relay, relay control components and other high-performance relays. The value chain of the relay industry is constantly extending to the high-end. In terms of product performance, it is developing towards the direction of more sensitive (low power consumption), smaller volume and higher performance (such as high-frequency relay).
