A connector latch, comprising: a first connector assembly (100; 200; 300) made of plastic and having at least a first surface on a first frame of the first connector assembly (100; 200; 300); a latch beam (104, 106) on said first connector assembly (100; 200; 300); a latch surface disposed on said latch beam (104, 106); and a button at a distal end of said latch beam (104, 106), said button has at least a first surface, said first surface of said button extends outward away from the button toward the general direction of the first frame, said connector latch being configured to be in one position selected from among at least an undeflected position, a transitional position, and a preloaded position, said first surface of said button is above said first surface on said first frame of the connector assembly (100; 200; 300) and said first surface of said button does not engage with said first surface on said first frame of the first connector assembly (100; 200; 300) when said connector latch is in said undeflected position, and the button and the latch beam (104, 106) being configured, such that said first surface of said button is below said first surface on said first frame of the first connector assembly (100; 200; 300) and is not engaging with said first surface on said first frame of the first connector assembly (100; 200; 300) when said connector latch is in said transitional position, and characterized in that the button and the latch beam (104, 106) being configured in order that said first surface of said button is below said first surface on said first frame of the first connector assembly (100; 200; 300) said first surface of said button engages with said first surface on said first frame of the first connector assembly (100; 200; 300) thereby locking said connector latch in said preloaded position. a first connector assembly (100; 200; 300) made of plastic and having at least a first surface on a first frame of the first connector assembly (100; 200; 300); a latch beam (104, 106) on said first connector assembly (100; 200; 300); a latch surface disposed on said latch beam (104, 106); and a button at a distal end of said latch beam (104, 106), said button has at least a first surface, said first surface of said button extends outward away from the button toward the general direction of the first frame, said connector latch being configured to be in one position selected from among at least an undeflected position, a transitional position, and a preloaded position, said first surface of said button is above said first surface on said first frame of the connector assembly (100; 200; 300) and said first surface of said button does not engage with said first surface on said first frame of the first connector assembly (100; 200; 300) when said connector latch is in said undeflected position, and the button and the latch beam (104, 106) being configured, such that said first surface of said button is below said first surface on said first frame of the first connector assembly (100; 200; 300) and is not engaging with said first surface on said first frame of the first connector assembly (100; 200; 300) when said connector latch is in said transitional position, and characterized in that the button and the latch beam (104, 106) being configured in order that said first surface of said button is below said first surface on said first frame of the first connector assembly (100; 200; 300) said first surface of said button engages with said first surface on said first frame of the first connector assembly (100; 200; 300) thereby locking said connector latch in said preloaded position.
