Vacuum relays and switches have characteristics that are well suited to airborne, marine and mobile communications systems, as well as fixed installation systems. The high dielectric strength of a vacuum is one of the important features which distinguishes vacuum relays from other types of relays. The use of vacuum as a contact environment increases the operating reliability and the life of the relay. Absence of oxygen prevents contact corrosion and the formation of oxides and organic materials, which can increase circuit resistance. Vacuum relays are distinguished by very low thermal and RF noise generation. Because the contact resistance of vacuum this relays is very low and stable, these units offer very low circuit losses. RF insertion loss is typically between 0.02 and 0.1 dB at operating frequencies.
