PDP11/03 BA-11M Front panel switch replacement

[Douglas Taylor via cctalk]

I have a BA11-M box with the usual front panel control, however it was 
damaged and all three switches have been sheared off.  The LED's and the 
circuit card that connects to the power supply appear to be OK.  I would 
like to repair it and put it back into service.  Is there a replacement 
for those switches?
