Abstract
A tub comprising a body for holding a volume of water. A tub system is coupled to the body to perform a function on the volume of water. At least a first circuit has a first circuit portion comprising at least one resistive switch mounted to a visible surface of the body and comprising at least a first resistive element adapted to be contacted by a bather, second circuit portion comprising a water detection sensor mounted to the body for containing liquid in the body above a given level, the first circuit being open between the first resistive element and the water detection sensor, an actuating closed circuit condition by which a bather in liquid above the given level closes the first circuit between the first circuit portion and the second circuit portion when touching the first resistive element. A controller is operationally coupled to first circuit portion and the second circuit portion of the first circuit, and to the tub system, the controller adapted to detect the actuating closed circuit condition to trigger an action of the tub system.
