Abstract
An electrical relay having two wettable electrical contacts, each supporting a conducting liquid. A wettable switch finger is moved from a non-deflected position to first and second positions by action of an actuator. In the first position the switch finger touches the conducting liquid and causes it to wet between the contacts and the switch and thereby complete an electrical circuit between the contacts. When the switch finger is in the second position, the conducting liquid cannot wet between first and second contacts and the switch finger and the electrical circuit between the first and second contacts is broken. The switch finger may be located at the free end of a beam that is deflected or bent by the action of piezoelectric elements.
