Mine dot is also known as pull point, and pull signal switch belongs to the same function, replace pull signal switch, suitable for underground coal mine, as low-voltage switch control explosion-proof bell and other small audio equipment, lighting signal device

Summary of structure

The signal switch is mainly composed of components such as flameproof housing, upper cover, connection cavity, terminal column, dynamic and static contact head, operating handle, etc. When working, the operating handle drives the shaft in the main cavity, making the moving contact head contact with the static contact head, forming a circuit and completing the connecting action. When the external force is removed, the spring makes it return to the disconnected position.
