Abstract
A microelectromechanical power relay uses mercury, or a similar liquid metal with high surface tension, as a flexible non-degrading contact mechanism. The basic systematic requirements for the micro-relay include large current carrying capacity, high speed, use of control voltages readily available in the given application, and an acceptable hold-off voltage. The preferred embodiment of the present invention includes the novel configuration of a liquid metal current carrying switching device.
