Abstract: An enhanced push-button includes a keycap disposed on an elastic member and having a top surface and an opposing bottom surface, and a reinforcing member mounted on the bottom surface of the keycap and having an outer surface facing the elastic member and an abutting portion located on the outer surface. The abutting portion has a contact surface recessed on the outer surface. The elastic member extends into the abutting portion such that the contact surface is abutted against the elastic member for allowing the keycap to be pressed with the reinforcing member against the elastic member to trigger a circuit switch. The invention can have better overall structural rigidity and operating feel and can maintain the pressing quality of the push-button and is suitable for low profile keyboards.
