Abstract
A dual condition responsive switch is shown including first and second discs each having convex-concave surface configurations on opposite sides thereof adapted to invert its configuration upon being subjected to selected conditions. A motion transfer member extends from the second disc to an electric switch. At a first range of conditions the first disc prevents actuation of the switch, at a second range of conditions the curvature of the first disc has inverted allowing actuation of the switch while at a third range of conditions the curvature of the second disc has inverted resulting in deactuation of the switch.
