Abstract
A method and apparatus for maintaining a liquid metal switch in a state of readiness for switching. The liquid metal switch has a liquid metal volume contained in a cavity of a switch body. A signal path though the cavity is made or broken by energizing an actuator to move the liquid metal volume within the cavity in response to a switching signal. To maintain readiness, a signal generator supplies a vibratory signal to the actuator. The resulting vibrations in the liquid metal volume allow the liquid metal volume to be subsequently moved with reduced power.
