Abstract

Un dispositivo detector de vibración, del tipo que comprende un miembro conductor eléctrico soportado normalmente en un asiento que incluye, por lo menos, dos elementos espaciados que forman contactos eléctricos, caracterizado porque el asiento está constituido por un par de placas eléctricamente conductoras (1) espaciadas, presentando cada una de estas placas una pista anular (2) formada por un orificio (3) simétrico entorno de su eje central, y el miembro eléctricamente conductor es una barra alargada (4) de sección transversal simétrica montada entre las placas (1) sobre las pistas anulares (2), siendo el área en sección transversal de la barra (4) con respecto al área del orificio (3) de modo que permita el movimiento de la barra (4) fuera de la pista (2) con la vibración del dispositivo.
