Document Type and Number:
Japanese Patent JP3152939
Kind Code:
B2
Abstract:
An impact detection device, in particular for a motor vehicle, includes at least one micromechanical acceleration switch having a contact element to be moved as a function of acceleration and a counter-contact element. A first voltage is fed to terminals of the contact elements by a monitoring circuit in order to detect an impact. A second voltage, through which the contact is closed on the basis of electrostatic forces of attraction, is fed in order to test the acceleration switch.
