<p>An electronic opening/closing device according to the present invention includes a housing; a fixing contact which is formed in the housing; a movable contact which is located in the lower part of the fixing contact, repeatedly touch the fixing contact and is repeatedly separated from the fixing contact; a shaft which is combined with the movable contact; a return spring which pressurizes the shaft downward; and a movable core which is combined with the shaft. The shaft has a pressing surface which faces downward. The upper end of the movable core touches the pressing surface. When the movable core and the shaft move up, the movable core pressurizes and elevates the pressing surface. When the movable core and the shaft move down, the pressing surface pressurizes and moves the movable core down.</p> |
