I haven't seen any with a switch that satisfies 680.12 under the skirt. "disconnect all ungrounded conductors" Often the skirt is screwed shut... Hardly accessable. Nor do I think you should be able to mess with said switch, if it had one, while in, or in contact with the tub. I think the idea was to have just about everything outside of 5' away from pools and spas including the disco. 680.41 would have you install a disco >5' within site, but for some reason doesn't apply to single family...
