ABSTRACT:
A tamper-proof elastomeric membrane device for secure electronic housings. At least one button is molded in this elastomeric membrane. The button is under pressure when the housing is closed to act on an electronic circuit, and the button is idle when the housing is open. The device can be applied to secure housings, such as in particular confidential code housings, whose physical integrity is sought to be guaranteed by a device for detecting opening.
