on the other hand coil 34 is of a significantly longer longitudinal dimension and extends one complete revolution about the base 31 and passes through aperture 36 totally around the entire base 31 and past aperture 36 back to aperture 45 in that coil 34 is significantly longer than coil 33 it can readily be seen that energizing of coil 34 causes significantly more heat to be transferred to the surrounding water within water chamber 12 if coil 33 is energized heat transfer will still occur but somewhat less heat will be transferred resulting in the issuance from water chamber 12 of somewhat warm rather than hot water referring to fig2 and fig3 each of the connectors 37 38 and 39 are connecting points for contact elements 47 48 and 49 respectively mounted on the upper surface of base 31 with reference to fig5 each of the contact elements 47 48 and 49 are specifically oriented for mating engagement with terminal contacts 50 51 and 52 extending downwardly from base 53 of the contact casing 14 this alignment is insured through the existence of a downwardly depending tongue element 54 positioned for mating engagement within a socket formed on the interior of structure 56 as the contact casing is mounted about its periphery to water chamber 12 to form a major portion of the housing means 10 with reference to fig5 insulative material disk or plate 80 is positioned within the contact casing 14 and the switch housing or.
