I seriously doubt that you will find an adapter of the type that you want. I have an old Omega SCA 400 analyzer that has a weird plug to the probe. I don't know what the circuitry would be that would include five conducters unless they are breaking both "legs" of the circuit with a "ground" conducter as well. KHBPhotographix has a manual for the timer that they are willing to sell for $12.00 (canadian). Perhaps it has a schematic that would enable one to determine how to make this work with a conventional floor switch.
