Abstract

1524404 Sealed contact devices KOMBINAT SCHALTELEKTRONIK VEB 16 Sept 1976 [19 Sept 1975] 38402/76 Heading H1N The co-operating contacts of a switch are contained in an enclosure which is sealed but has a wall permeable to oxgygen so as to maintain a predetermined oxygen content of the protective gas within the enclosure. The wall may be made of a plastics material such as polyamide or of a ceramic material. The enclosure may have insulating or metal shields to prevent metal vapour, due to arcing being deposited on the walls of the enclosure.
