Title:
ACTUATOR AND RELAY
Document Type and Number:
Japanese Patent JPH113646
Kind Code:
A
Abstract:

To provide an actuator capable of realizing size reduction, power consumption reduction, and integration, and to provide a relay having large dielectric strength for an opened contact and small contact resistance for a closed contact by using the actuator.

This relay has a piezoelectric body 36, a contact electrode 22, a piezoelectric actuator 18 having displacement means 38, 40 for displacing the piezoelectric body 36 in the x direction, a piezoelectric body 30, a contact electrode 16, and a piezoelectric actuator 12 having displacement means 32, 34 for displacing the piezoelectric body 30 in the (y) direction. When a contact is to be closed, the contact electrodes 16, 22 are connected by displacing the piezoelectric actuator 18, and, when the contact is to be opened, the contact electrodes 16, 22 are separated in the (y) direction by displacing the piezoelectric actuator 12.
