Indicator Lamp Series

1. Brief Introduction of Push button:
AD22-22-25-16(LED) and AD22-22-25-16-12 series of indicator is equally used LED shining chip as light source. Because of long life,low consumption,small volume and light weight,It is a product replaced the older kind of incandescent lamp and indlcator of neon lamp by new ones.AD22-25,AD22-22 and AD22-16 indicators are produced by our factory enjoying following characters;high brightness,good rellabillity beautifu shape and careful manufactured.Products are well praised by lots of cllents.Inorder to fit in with top quality and aesthetic demand of user,we develop AD22-22B,C,D,E,G,Hdouble-color lamp,position indlcator,shining buzzer and miniature short indicator,as well as design shape of polycarbonate witj high intension and enjoying better anti-surge pergomance,and bolt-type connector designed will make it safer and more convenlent.All improvement will be provided to make your choice more convenlent and your deslgn perfect.

2. Push button usage:
AD22series of indlcators are used as indicating,foretelling,accident and other signals in the lines of equipment (such as electrical power,telecommunication,machine tool,watercraft,textile,printing and mine machinery,etc).

3. Type of Push buttons:

4. Applicable environment of push button:
(1)Surrounding temperature:-25ºC–+55ºC.

6. Circuit Introduction of push button
(1)AC and DC indicator(DC/AC6V~220V)Note:It should be considered radiating condition When DC is up to 110v,220v and 380v,for there is a great of heat.
(2)AC indicator (AC 220V,AC380V)
(3)Return of double-color indicator(DC,Ac110-220V)
