Which mixer do you have?  I can't even work on an answer if I don't know which mixer it is.  Do you think it is foot switch controllable?  Or are you wanting to mod one in.

If you want to mod one in you would put a foot switch in SERIES with the in/out switch for the effect you want to control.  That way both switches have to be on for the effect to work and can be foot controlled just by leaving the deck switch always on.
Unless it uses electronic switching then we are out of my field unless you have a full schematic.
