SEMI's preliminary estimate shows that in April, North American semiconductor equipment manufacturers received a global average of US$1.5983 billion in three-month moving orders, an increase of 1.1% from the revised value of March (US$1.5808 billion), and compared with 2010. The 1.44 billion U.S. dollars in the same period of the year was 10.8% higher.
In April, North American semiconductor equipment manufacturers’ initial estimate of the three-month moving average shipment amounted to US$1.632 billion, which was 1.6% less than the revised value of March (US$1.6575 billion), but was 27.4% higher than the US$1.28 billion of the same period in 2010. .
Daniel Tracy, senior director of SEMI's industry research data department, said that the industry’s current orders and expenditures are in line with the 2011 capital expenditure plan that has been announced. Intel Corporation, the leading semiconductor manufacturer, announced on April 19 that its capital expenditure budget for 2011 will be as high as $9.8 billion to $10.6 billion, which is higher than the original forecast of $8.7 billion to $9.3 billion.
Push Button Switches
The Push Button Switches, also known as the control button (referred to as the button), is a low-voltage electrical appliance that is manually and generally can be automatically reset. The Push Button Starter Switch is usually used to issue a start or stop command in the circuit to control the turning on and off of electrical coil currents such as electromagnetic starters, connectors, and relays.
The On Off Push Button Switches refers to a switch that pushes the transmission mechanism with a button to make the movable contact and the static contact open or close and realize circuit switching. It is a master control device with a simple structure and a wide range of applications. In the electrical automatic control circuit, used to manually send control signals to control connectors, relays, electromagnetic starters, etc.
This Pushbutton Switches is a kind of electric device that is used to switch on and off the small current circuit when the action is released. Generally used in AC and DC voltage below 440V, the current is less than 5A in the control circuit, generally do not directly manipulate the main circuit can also be used in the interconnection circuit. In actual use, in order to prevent desperation, different marks are usually made on the buttons or painted with different colors, and the colors are red, yellow, blue, white, black, green, and the like.
The Momentary Push Button Switch could be divided into metal push button switches and LED Light Switches and ordinary snap button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, with indicator light type, lighted symbol type and key type, etc., with single button and double Buttons. Generally, it adopts a water-storage structure, which consists of a button cap, a return spring, a static contact, a moving contact and a casing. It is usually made into a composite type, and has a pair of normally closed contacts and normally open contacts, and some products can pass. The series connection of multiple elements increases the number of contact pairs. There is also a self-contained button that automatically holds the closed position when pressed, and can be turned on only after the power is turned off.
When the Metal Switches is not pressed, the movable contact is connected with the upper stationary contact. The pair of contacts is called a normally closed contact. At this point, the movable contact is disconnected from the following static contact. The pair of contacts is called a normally open contact: the button is pressed, the normally closed contact is open, the normally open contact is closed, and the button is released. Restore the original working state under the action of the return spring
