An electrical relay comprising having two wettable electrical contacts supporting
a conducting liquid. A non-wettable switch finger is moved between first and second
positions between the electrical contacts by action of an actuator. In the first
position the switch finger permits the conducting liquid to bridge the gap between
the contacts and complete an electrical circuit between the contacts. In the second
position the switch finger separates the conducting liquid into two volumes, breaking
the electrical circuit between the contacts. The switch finger may be located at
the free end of a beam that is deflected or bent by the action of piezoelectric elements.
