<p>The device (100) has a pivoting arm (130) driven by movement of a float (102) and selectively acting on monostable micro-switches (110, 120) to define three states i.e. rest, active and alarm states, of the device. The micro-switches respectively have push buttons (112, 122) movable between stable and unstable positions. A security action is triggered, the button (112) is in the unstable position for assuring operation of a condensate-lifting pump, and the button (122) is in the stable position for assuring triggering of the action, in the alarm state. The pump is stopped in the rest position.</p> |
