Zusammenfassung:	A ruggedized electronic device includes a case and an enclosure within the case. The case provides a first level of explosive atmosphere protection to components within the case. The enclosure provides a second level of explosive atmosphere protection to the components within the enclosure. The second level is higher than the first level. The enclosure includes a main board within the enclosure, and a switch. The main board includes a connection from within the enclosure to the case. The switch provides the connection to the case in a first switched mode and isolates the connection from the case in a second switched mode.
