First of all, these are bi-directional actuation with high forces, a very low contact resistance and good heat dissipation. The present work describes the reliability of a surface-micromachined ohmic switch with gold contacts, combining all this features. Hot switching of 50mA at 10Vdc is possible in ambient air for more than 50 million cycles. With a load of 10mA more than 100 million cycles have been demonstrated repeatedly.enMEMS switch with prolonged lifetime under hot switching conditions based on gold as contact materialconference paper
