Definitions
- Some examples of such design and operational aspects are the bimetallic disc materials, the offset distance 134, the case stability or stiffness, the disc seat stiffness, the surface finish of the disc seat 110, relaxation or redistribution of residual stresses in the structural components of the thermal switch, and the effects of wear and/or abrasion.
- the temperature set point drift decreased by about 50% after 100,000 simulated operational cycles compared to the measured drift in a thermal switch without a disc seat 110.
