Summary:The utility model discloses an isolating switch for a high-voltage electrical distribution device in a coal mine, which belongs to the mechanical switch mechanisms; and the utility model solves the technical problems that a high-voltage switch still reserves residual voltage at an output terminal and at an input terminal of a high-voltage circuit breaker after separating brake of the isolating switch, so that the electric shock accidents are easily generated when the worker overhauls the device. The isolating switch comprises a switch box body (1), an isolating plug (3), a movable isolating plug (4) and a manual driving lever (5) of the movable isolating plug (4), an electroconductive plate (11) is fixedly arranged at the front end of the movable isolating plug (4), an earth clamp of the electroconductive plate (12) is fixedly arranged at the lower end of the electroconductive plate (11), an earth terminal (10) is arranged on the switch box body (1), an earth clamp of the movable isolating plug (9) is fixedly
