Sealed relays intended for high-voltage or high-power switching are enclosed in a hermetically sealed plastic housing or jacket (11) capable of long-term maintenance of either a high vacuum or a pressurized insulating gas within the relay to suppress contact arcing during switching. The impermeable plastic housing eliminates need for conventional glass or ceramic contact enclosures, and enables use of inexpensive relays (71) in demanding applications.
