PURPOSE: An apparatus for pushing a tact switch of an electronic product is provided to efficiently operate each tact switch without interfering in each other by using a signal operation button when a plurality of tact buttons are installed on a narrow space. CONSTITUTION: A plurality of tact switches are installed to be distanced from each other by a predetermined angle, maintaining uniform intervals from a central point on a sub PCB. A button installing groove(22) having a predetermined size is formed on a portion of a surface of a housing. The portion corresponds to a position where the respective tact switches are installed. A plurality of push sections(30) have self elasticity and are formed on positions corresponding to the respective tact switches from the center on a bottom surface of the button installing groove. An operation button(40) is inserted into an inside of the button installing groove from an outside of the housing to be coupled to the button installing groove. The operation button(40) is integrally formed with an operation protrusion which is contacted with upper parts of the push sections along edge portions on an inner surface of the operation button.
