power to any part of the humidifier 100 occurs as such the gfci circuit 236 opens the switches 204 208 and prevents power from being applied to the humidifier 100 it should be understood that the circuitry 200 of fig6 is purely exemplary other circuitry could be used in light of the teachings herein to provide for the safety features of the humidifier 100 of the present invention for example the reference sensor 296 comprising an exposed electrical conductor could be eliminated and providing for proper for providing for proper sensing of low and high water conditions further silicon controlled rectifiers could be substituted for transistors q 1 280 and q 2 248 in this case diode d 1 272 could be eliminated also the overheat sensor 164 could be eliminated and a self regulating temperature heating element could be used further the telescoping enclosure embodiment of the travel humidifier 100 has been described as including a pair of slidable arms 196 for contacting the housing 128 of the water reservoir 112 however it should be understood that these slidable arms are purely exemplary other means for contacting the housing of the reservoir may be utilized if desired in light of the teachings herein the arms 196 are made slidable in that if the arms are pushed in on both.
