A previously developed computer model of the dynamics of hand-operated rocker switches is used with the aim of reducing pivot bounce and erosion. The method used is to study the kinetic energy at the instant of main contact impact, showing how the energy is affected by the force applied to the switch and how it relates to the switch dimensions. Some possible modifications are suggested. These are compared in experiments using a low-current source. In the experiments the pivot bounce times are measured and compared to the computer-predicted values of kinetic energy, demonstrating the relationship between energy and pivot bounce and showing how a reduction in energy reduces bounce. When a load current flows, a reduction in the bounce time duration is observed. The results are presented of the reduction at 12-A dc for various mechanical bounce times.
