Abstract
An improved snap action valve construction is disclosed in which a compensator blade has deflection resisting ribs positioned along a weld line defined between an active blade and the compensator blade. Additionally, the compensator blade may have a recessed tab for securing a spring between the compensator blade and a snap blade. In one embodiment, the snap blade includes one or more longitudinal recesses to increase the deflection of the snap blade in the area of the recesses. In another embodiment, the snap blade has an arc-shaped rib surrounding a portion of a valve member opening. The arc-shaped rib resists flexing of the snap blade in the area of the opening.
