Title:
PIEZOELECTRIC RELAY
Document Type and Number:
Japanese Patent JPS63308838
Kind Code:
A
Abstract:

PURPOSE: To secure such a piezoelectric relay that is resistible to dust and humidity by supporting and fixing the piezoelectric unimorph fitted with a traveling contact, while casing the unit fitted with a fixed contact and input- output terminals in a casing case.

CONSTITUTION: A sheetlike piezoelectric element is stuck to a conductive flexible plate 7 of metal or the like. A piezoelectric unimorph 5 similar to a disc or a round form, being fitted with a traveling contact 8 is supported and fixed, while a piezoelectric relay unit being fitted with a fixed contact and input-output terminals 11 is case in a casing, covering this piezoelectric unit. Here at the time of supporting and fixing the unimorph 5 directly to a flat surface of a support part 9a of a mount 9, when one thid of the outer diameter is supported and fixed, displacement and displacement load of the unimorph 5 can be efficiently taken out.
