PURPOSE: An apparatus for enhancing shake of a PBA(Printed Circuit Assembly) mounted on an SSW(Space Switch) rack of an MSC(Mobile Switching Center) is provided to prevent a serious failure of an MSC by fixedly mounting a PBA on a shelf of a SSW rack and forming an engaging jaw at a lever of an ejector and a locker. CONSTITUTION: A lever(38) having a slope and narrowing width is extendedly formed in a longitudinal direction of a main body(31), and an engaging jaw(38a) is formed bent by 90-degree angle at an end portion of the lever(38). A locker(32) is integrally formed with a handle(34) at a right angle to the main body(31) and coupled to the main body by being elastically supported by a spiral spring. An engaging jaw(32a) is formed bent at a 90-degree angle at an end portion of the locker(32). A power protrusion(36) having a switching recess(36a) is protrusively formed at a middle portion of the main body(31). A rotation hole(39) is formed at a portion of main body(31) where the lever(38) is formed in order to couple a PBA ejector(30) to a PBA so as to be rotated by 180 degrees.
