This specification discloses a polymer spring including an elongated shank having a first end with a longitudinal slit and an enlarged portion, an integral enlarged head at a second end of the shank opposite from the first end, and an integral, cupped flange for providing a biasing force surrounding the shank and opening toward the first end. Deflection of the flange creates a biasing force tending to cause the flange to return to an undeflected state.
An electrical contact switching device comprising: a support board for supporting a switch button; an aperture in said board; electrical contacts on one side of said board adjacent said aperture; an integrally molded polymer contact button including a shank projecting through said aperture, conductive means on said shank adjacent said electrical contacts; said shank having a first end with an adjustment means for reducing the circumference of said first end for passage through said aperture and for increasing the circumference of said first end for resis...
