BAX-5/127A(63S1) Mining explosion-proof signal switchDetailed product description：

Scope and Application
The BAX-5/127A (63S1) mining explosion-proof signal switch (hereinafter referred to as the signal switch) is suitable for underground coal mines with explosive mixed gases of methane and coal dust. It is used as a low-voltage switch to control explosion-proof electric bells and other small audio equipment, as well as the connection and disconnection of lighting signal devices. It can also be used as a signal point device for underground lifting systems.  

The signal switch is designed, manufactured, and inspected in accordance with standards such as MT625-1996 "Explosion proof Signal Switches for Coal Mines", GB3836.1-2000 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements", and GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion proof Type" d ".
Structural Overview

The signal switch is mainly composed of a flameproof housing, an upper cover, a wiring chamber, a terminal post, dynamic and static contacts, a torsion spring, an operating handle, etc. During operation, the main chamber shaft is driven by the operating handle, forming a circuit between the moving and stationary contacts to complete the connection action. When the external force is removed, the torsion spring returns it to the disconnected position.
