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.

A snap action switch, comprising: an electrically conducting terminal plate having at least one aperture formed therethrough; an electrically conducting stationary contact spaced from said terminal plate; an electrically conducting contactor means disposed between said terminal plate and said stationary contact, said contactor means including a snap action dome having at least one cantilevered spring arm for supporting the dome in a stable position in spaced relation to said stationary contact and in conductive contact with the terminal plate; and pushbutton means mounted over said terminal plate for engaging said dome through said aperture and flexing the dome away from the terminal plate and against the stationary contact when the pushbutton means is pressed, the dome returning to its stable position when the pushbutton means is released.
