Device for detecting the opening of a hatch in an item of equipment comprising one or more electronic circuit boards

An item of equipment, comprising:

• a case;
• a hatch for closing the case;
• one or more electronic circuit boards having a plane which is substantially orthogonal to a plane containing the hatch;
• and
• a device for detecting an opening of the hatch, wherein:
• the device comprises a detection circuit and a conductive element,
• at least one of the one or more electronic circuit boards comprises at least two conductive parts electrically insulated from one another and each of the at least two conductive parts is connected to the detection circuit,
• the conductive element is attached to an inner side of the hatch,
• a portion of each of the at least two conductive parts is flexible and extends laterally to a side of an edge of the one or more electronic circuit boards which is proximal to the hatch,
• the portion of each of the at least two conductive parts is a preformed metal stem, strip or tongue curved in a U-shape having two branches,
• the two branches of the portion of each of the at least two conductive parts are substantially parallel to the hatch, and
• the conductive element faces the at least two conductive parts and comes into contact with the at least two conductive parts when the hatch is in a closed position.
