The invention relates to altimeter triggers used in particular for triggering devices for bomb braking or for deploying cargo bombs or rockets. The aim thereof is to achieve correct triggering in the event of low-altitude release both with and without pulling-up. It consists, for an altimeter trigger, in making provision for an activation phase, during which there is imposed a triggering set-point level changing progressively from an almost zero value to the nominal triggering level. In the altimeter trigger shown an altimeter probe (1) delivers an electrical voltage proportional to the measured level, a threshold voltage source (2) delivers a voltage proportional to the nominal triggering level, a threshold voltage progressive application circuit (3) produces an output which rises from zero to this level and a comparator (4) compares the measurement voltage with the output of the circuit (3). |
