electrical ignition pyrotechnic trap is the destruction of pests of moles and similar size and behaviour

摘要

A pyrotechnical mole trap includes an open-ended protective envelope which is intended to be placed in the mole run, a displaceable trigger of electrically conductive material disposed in the center of the protective envelope and displaceable in both directions to contact one of two contacts and close a circuit, two electrically fired deflagrating explosive charges, of which each is placed on the outside of the protective envelope, a source of electric energy, an electrical circuit which connects together the trigger, the electrical contact, the explosive charges and the source of electrical energy and which is wired in such a way that the action of the mole on the trigger closes the electrical circuit and fires the explosive charge situated on the animal side of the trigger.
