Overvoltage protection device with simplified display system and corresponding production method

A device (1) for protecting an electrical installation from overvoltages, having at least one protection component (2) and disconnection means (3) capable of changing from a closed configuration to an open configuration, as well as signaling means (5) capable of indicating the configuration of the disconnection means (3). The disconnection means (3) and the signaling means (5) respectively comprise a mobile disconnection element (4) and a mobile signaling element (12) arranged such that, when going from the closed configuration to the open configuration, the mobile disconnection element (4) moves in a rotational movement according to a first trajectory and cooperates with the mobile signaling element (12) to drive the mobile signaling element in rotation along a second trajectory different from the first trajectory.
