This invention relates to a switch lock for switch tongues (2, 3) having at least one locking piece (6, 7) for attaching to a stock rail (4, 5), having at least one switch tongue attachment (8, 9) for attaching to a switch tongue (2, 3) and having a slide rod (10), wherein the adjustment distance of the slide rod (10) is greater than the switch tongue impact (Z) of the switch tongues (2, 3), and in its end position, the switch tongue (2, 3) is locked on the stock rail (4, 5), wherein at least one bearing roller (17, 18) is provided on the locking piece, and wherein the slide rod (10) can be moved relative to the locking piece (6, 7) by means of the bearing rollers (17, 18) to adjust the switch tongue (2, 3). In order to make a switch lock available wherein only minor actuating forces which are essentially constant are necessary and wherein the maintenance and lubrication costs are minimized, it is provided according to this invention that an angle lever (19, 20) be provided, said angle lever being connected to both the slide rod (10) and the switch tongue attachment (8, 9) and rolling on the bearing roller (17, 18), and the angle lever (19, 20) work together with the bearing roller (17, 18) for locking and/or adjusting the switch tongue (2, 3), so that the angle lever (19, 20) pivots with its free end about the articulation point on the switch tongue attachment (8, 9) in adjustment of the slide rod (10) in the locked state of the switch tongue (2, 3).
