<p>PROBLEM TO BE SOLVED: To reduce the number of part items, miniaturize a switch, and shorten the switching time by providing at least two switching elements, fixing at least one switching element to a relatively movable driving portion, and forming the driving portion with a solid type energy transducer. SOLUTION: Contact point springs 2, 3 are supported in a switch Y-24, and end sections of the contact point springs 2, 3 protruded from the switch Y-24 form a current connection section. The longer spring 2 is fixed to an energy transducer 7, the contact point spring 2 is elastically curved when the energy transducer 7 is deviated, and its contact point member 5 is brought into contact with the contact point member 6 of the contact point spring 3. When a driving portion is formed with the energy transducer 7 made of a ferroelectric piezoelectric ceramic, the number of part items of the switch Y-24 is reduced, and the switch Y-24 can be miniaturized.</p> |
