What kind of transducer are you working on? Does it really have such a big magnet that you can't keep the reed switch portion of the handpiece far enough away from the magnet to prevent this from happening? Many soldering devices use a similar mechanism. Metcal irons usually have magnets in their holder and will go into a low-power mode when the handpiece is in the holder.
