Founded in 2001, Shanghai Yongming Electronics Co., Ltd. is committed to the research and development and production of aluminum electrolytic capacitors in the field of light sources. It has obtained 16 national patents. And has a team of technical experts at home and abroad to form their own research and development center.
It is understood that the monthly production capacity of Yongming Light Source Aluminum Electrolytic Capacitor reaches 120 million, and the product is 100% matched with the light source. LED driver power supplies have different application links, and the requirements for electrolytic capacitors are also different. Yongming also displayed a full range of products with different requirements in different environments.
This time, Yongming launched a full range of aluminum electrolytic capacitors for LED drive power, with a high temperature resistance of 125 degrees. “Yongming is best at miniaturization, long-life aluminum electrolytic capacitors, which can directly replace Japanese imports in terms of product performance, form factor and ripple resistance,†said Wang Yongming, chairman of Yongming Electronics.
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
