Summary :

A movable electrode in conventional electromechanical contacts often shows a bounce against the opposite electrode during a make and break operation. Frequent bounces are troublesome. We studied this phenomenon with conventional reed switches using a slowly increasing and decreasing driving current. Judging from the measured data, Coulomb's electrostatic force cannot be neglected in efforts to suppress bounce.
