[sdiy] BBD Delay Kit Question

[Prototek]

    I have two little BBD delay kits laying around here. I think they're
made by CanaKits or something?
    Anyway... like I said, I have two. I was wondering if it's possible to
run them in series by wiring the 1st one's output to the 2nd one's "input
solder pad." My ideal plan would be to run the 1st output to a switch and be
able to toggle between sending it to the 2nd delay or just using it alone.
Is this possible? Would I need a SPDT or a DPDT? I'm really uneducated when
it comes to switches and I'd appreciate any info.

                Thanks,
                John
