Abstract
A snap action double throw switch has a dome-shaped switching element which is responsive to a downward pressure to flex downwardly into conductive contact with an underlying contact element. When pressure is removed, the dome snaps back to a stable position and thereby breaks contact with the contact element. In the stable position a spring arm of the dome element presses the top surface of the dome against an overlying conducting plate.
