ABSTRACT:
A bridging contact abuts one end of a piezoelectric bar and is held across a pair of current carrying fixed contacts by means of a compression spring to assure a good electrical conductive path across the fixed contacts. To separate the contacts, a voltage pulse is applied to the piezoelectric bar in a direction transverse to its linear extent. The rapid expansion of the piezoelectric bar drives the bridging contact rapidly away from the fixed contact pair to interrupt the current therethrough.
