Modern Impedance Selector Switch (Replacement for Marshall® Amps)

Pro: has very good selection lock and appears to make good contact. Con: the design locks the halves together with rivets which also serve as the mounting holes but the holes are too small for the original brass screws. This might seem picky but the mfr doesn't supply any screws that fit. Nevertheless we're probably lucky to have any mfr still making these because if yours breaks, the alternatives are ugly.
