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.
