It is possible to construct a cheap T-switch using a Bud MiniBox or other
chassis, 3 DB-25 connectors, and a two position, multipole (in your case 5P)
rotary switch. The total cost should be under $35 using new parts; cheaper
if you locate a surplus out. I have constructed several of these units
since I found that >$100 to be rather outrageous. This greater expense is
probably due to the fact that most of these units switch around 23 lines,
and such switches are expensive (and unneeded in most cases).
