Figured it out. Thanks to all ;} Right under the rear plate (4 screws) of the Lekato Looper Pro there are four contacts where the switch meets the board. Ohmmeter proved them to be "normally open" and that they were paired (two X, two Y). Shorting them activated the looper's record, play and erase as expected. Soldering in a "normally open" foot switch will be easy as there's plenty of space for a drilled hole and cable snaked through. Now I can use an ergonomic, light-action, full-size foot switch instead of that dopey protruding thing with all its extra wasted motion before it makes contact.
