Definitions

  • the test electrode is connected to the counter contact piece close to the acceleration switch, so that in each case only two conductors are required between the monitoring circuit and the acceleration switch.
  • the first voltage supplied by the voltage source and applied between the contact pieces or contact piece and test electrode is by no means so great that the contact pieces are deflected by the electrostatic attractive force until the acceleration switch closes.
  • the amount of the second voltage necessary for the induced closing of the acceleration switch is greater than the amount of the first voltage.

Abstract

Selon l'invention, un dispositif de reconnaissance d'impact comporte au moins un commutateur d'accélération (11) constitué selon la technologie de la micromécanique, pourvu d'une pièce de contact (111), se déplaçant en fonction de l'accélération, et d'une contre-pièce de contact (112). Pour permettre la reconnaissance d'un impact, une première tension (USS1) est conduite par un circuit de surveillance (3) jusqu'aux bornes (1111, 1121) des pièces de contact (111, 112), tandis qu'une seconde tension (USS2), par laquelle le contact (111, 112) est établi grâce aux forces d'attraction électrostatiques, sert à tester le commutateur d'accélération (11).
