Title:
電源内蔵式スイッチング装置
Document Type and Number:
Japanese Patent JP4813005
Kind Code:
B2
Abstract:
A self-powered switching device using a prestressed flextensional electrocative member (12) generates a signal for activation of a latching relay (90). The electroactive member (12) has a piezoelectric element with a concave face that may be compressed to generate an electrical pulse. The flextensional electroactive member (12) and associated signal generation circuitry (10) can be hardwired directly to the latching relay (90) or may be coupled to a transmitter (60) for sending an RF signal to a receiver (70) which actuates the latching relay (90).
