Abstract: A push button assembly includes a female member comprising a base and a socket integral with the base, a male member movably mounted to the female member, and a resilient member. The male member includes a pressing portion and a positioning portion extending downwards from a lower surface side of the pressing portion. The positioning portion is captive in the socket. The male member is movable between a first position and second position. The resilient member surrounds the positioning portion. When a push force is applied to the pressing portion of the male member, the resilient member is deformed and the male member is moved to the second position. When the push force is released, the resilient member recovers and drives the male member to move to the first position, but the resilient member is always constrained to undergo compression and release along its own central axis.
