Abstract: A low cost, sealed contactor comprises a hermetically sealed housing with a flat header having internal components for changing the state of said contactor. Terminals are electrically connected to the internal components for connection to internal circuitry and applying an electrical signal to control the state of the contactor. A solenoid-driven plunger with a hollow shaft is included. Power-reducing electronics located within the hermetically sealed housing are also included. Two contact springs are also included to improve electrical performance. O-rings are added to help seal the contactor and keep it hermetically sealed.

Abstract: A high voltage relay comprises a hermitically sealed housing made of ethylene vinyl alcohol (EVOH) and having internal components for changing the state of said relay. Terminals are electrically connected to the internal components for connection to external circuitry and applying an electrical signal to control the state of the relay. A nitrogen and sulfur hexafluoride gas fills the housing to allow for reliable high voltage operation with the housing having low permeability to the molecules of the gas.
