Mine explosion-proof and instrinsically safe type acousto-optic signal switch

1.High-brightness light-emitting diodes 2.Explosion-proof and Intrinsically safe type 3.Structure is simple and reasonable

1. Application Scope: 

 

Acousto-optic signal switch is applicable to the signal contact of belt transport and winch transport in coal mines containing explosive gases; it facilitates production and improves economic efficiency, having great promotion prospects and values. Such combination signal switch is much more advanced than the original bell one and other signal ones from domestic and foreign manufactures.

 

2. Products Features

 

It is light, combing with several functions such as little button, explosion-proof lights,

explosion-proof lights, explosion-proof electric bell, three wiring etc. the original explosion-proof lights are replaced by high-brightness light-emitting diodes, unique and visual; the original bell is replaced by the current high-frequency horn, high-sound frequency, distant transmission. The explosion-proof cavity of the switch has a separate connecting cavity with four outlets. The overall structure is simple and reasonable.
