The training mine for military personnel comprises a casing (7) with at least one side wall (8), a bottom plate (9) and a cover (10) provided with a movable sensitive unit (11) for transmission of forces applied outside the mine to the miner interior. The sensitive unit transmitted forces activate a switch (16) inside the mine to close an electrical circuit (2) to which an indicating unit is connected at a distance from the mine. The sensitive unit is transversally movable against the force of a spring (12) in order to activate the switch. The switch is arranged to remain in the activated position. A reset passage (19) is arranged in the bottom plate so that with an object the switch can be reset to the inactivated position. |
