SYSTEM AND METHOD FOR AVOIDING CONTACT STICTION IN MICRO-ELECTROMECHANICAL SYSTEM BASED SWITCH

摘要

A system that includes micro-electromechanical system switching circuitry, such as may be made up of a plurality of micro-electromechanical switches, is provided. The plurality of micro-electromechanical switches may generally operate in a closed switching condition during system operation. A controller is coupled to the electromechanical switching circuitry. The controller may be configured to actuate at least one of the micro-electromechanical switches to a temporary open switching condition while a remainder of micro-electromechanical switches remains in the closed switching condition to conduct a load current and avoid interrupting system operation. The temporary open switching condition of the switch is useful to avoid a tendency of switch contacts to stick to one another.
