Abstract
A pyrotechnical mole trap includes: An elongate protective envelope which is open at its ends and which is intended to be placed in the mole run, An electrical contactor placed inside the protective envelope, Two displaceable triggers mechanically controlling the electrical contactor, each of these triggers being placed at one of the ends of the protective envelope, Two electrically fired deflagrating pyrotechnical charges, of which each is placed on the outside of the protective envelope near each of the triggers, A source of electric energy, An electrical circuit which connects together the electrical contactor, the pyrotechnical charges and the source of electrical energy and which is wired in such a way that the action of the mole on either of the triggers closes the electrical circuit and fires the pyrotechnical charge situated in the immediate proximity of that trigger.
