Abstract
A micromechanical switch having a plurality of stable positions, which can be driven between the stable positions with a minimum of residual oscillation. The low oscillation results from the application of a braking force of specific magnitude and duration to exactly cancel the excess energy imparted to the switch during actuation. The braking algorithm results in a faster settling time, thereby improving the performance of the switch.
