Rotary switch in Boss NS-2

[gutsofgold]

It's an ALPS 534. From what I can tell (without a schematic) it's a 2 pole 2 position switch (DPDT) switch. Does anyone know where I can find a replacement? Mouser does not stock the correct one.

Might be tricky to find one with the spline shaft.  Could use a DPDT toggle switch.  Or just hardwire it to the noise reduction setting vs the rather useless mute setting.
