It would work for relay or appliance type switches but not for two dimming products. The dimmers work by chopping the sine wave of the output, chopping a chopped sine wave causes problems and most of the time switch destruction. If you had an appliance switch and then a dimmer, that would work but not two dimmers. This is the same reason you run into problems trying to dim low voltage lights with most electronic transformers.
