ABSTRACT:
A snap-acting positioning device comprising an enclosure, including a spring member having a plurality of sine-shaped bow sections disposed equidistantly in a circular pattern to take a disc shape and stressed to cause the spring member to take a substantially dome-shaped configuration and the sine-shaped bow sections to store a predetermined amount of energy. The spring member is made of flexible material and is adapted to co-act with an activating member to define a snap-acting function. The snap-acting device is capable for employment in snap-acting valves, snap-fasteners, linear positioning devices, vibration and shock reduction hardware and spring suspensions for rotating machinery.
