Dongguan Yinyin Hardware Products Co., Ltd. is a one-stop service enterprise integrating production, service, sales and after-sales. Welcome buyers to negotiate! Industrial Automatic Fast Rolling Up Doors
Industrial automatic fast rolling doors are
widely used in all kinds of factory and warehouses. Such fast action doors can
open and close in very short seconds, to improve efficiency obviously.
At the same time, fast roll up doors can prevent dust entering rooms and keep clean inside building.
Thanks to the manufacturer of professional silver contacts (in-mold riveting parts), stamping parts, low-voltage switches (wall switches, leakage switches, etc.) that focus on "safety electricity, safety switches, safety electricians"! Thank you for your attention! ! Committed to providing users with the most comprehensive safety power detail service!
1. About the contact (or contact)
For the frequent energization at 220V, the contact function is to reduce the contact resistance, reduce the arc, and increase the service life. Without the contact, it is actually very dangerous. For example, the general 220V 10A rating. In the case, the contact should be at least 2.5 mm in diameter.
2. The arc, the term is actually familiar to everyone, but in the propaganda of many products, even the propaganda of some big brands that everyone is familiar with is propagating this is to extinguish the arc, in fact, the arc is impossible in such a machine is In the switch, in fact, there are really, can be achieved, such a switch called, thyristor switch (people who have learned industrial control know), so the wall switch used by our people, this is impossible, When the two charged conductors are in contact or separated, when the voltage reaches 12-20V and the current is 0.25-1A, the arc can already be generated.
3. The material of the contact, in fact, there are too few people to understand this, but if it is toxic, everyone may pay attention to it. Most of the wall switch contacts on the market today are silver-cadmium alloys. And this cadmium is very toxic. He directly affects the most important organ in the human body. The kidney is telling everyone a new term, called ROHS. In fact, now Europe has long banned such metals in electrical products. Used in the middle, and how many of our people know?
4. Switch structure, now we go buy a switch, always pick a touch, in fact, the structure of the switch determines the feel of the product, and the structure of the switch is actually the most important, the switch sold throughout China is basically a bridge structure The internal structure is like a seesaw. Only by sliding friction can the product's switching function be realized, but everyone thinks that this sliding is in the case of electrification, and the Chinese market estimates that there are less than 1% of the brand's walls. The switch adopts a pendulum structure, and the structure is truly changed from sliding friction to axial (or rolling) friction.
5. The thickness of the copper sheet,
The requirement in the industry is to be greater than 0.6-0.7 mm
6. Clearance
No matter between the two terminals with different polarities, whether it is a straight line or a space distance of not less than 3 mm
7. Wiring screws,
Copper screw this material is more suitable
