An improved railroad switch apparatus includes a switch machine (26), a locking system lug (8), a detection system lug (12), a lock rod connecting rod (34), a point detector connecting rod (44), a pair of movable rails (22, 24). The locking system lug (8) is mounted on a pair of lock rods (30, 32) of a switch machine (30, 32), and the detection system lug (12) is mounted on a point detector rod (40) of the switch machine (26). The locking system lug (8) includes a groove (60) that receives the lock rod connecting rod (34) and that permits a slight degree of pivoting therebetween while remaining securely mounted thereto. Similarly, the detection system lug (12) includes a groove (160) that receives the point detector connecting rod (44) and that permits a light degree of pivoting therebetween while remaining securely mounted thereto. The locking system lug (8) and the detection system lug (12) each include a pair of opposed convex retention surfaces (80, 84) formed on the groove thereof.
