<p>The water heater comprises a tank having heating elements (2, figure 1), an inlet and outlet pipe (3,4, figure 1), a control mechanism (5, figure 1) and a rotating bracket 58. The mechanism controls power to the elements and includes a first 51, second 52 and third 53 housing. The first housing has a water inlet 511 connected to the inlet pipe, a water outlet (512, figure 3) connected to the water tank, and a first 54 and second 542 watertight ring. The first ring allows water flow between the inlet and outlet when in a first position proximate a base plate 50 and prevents water flow when in a second position distal the base plate. An aperture (541, figure 6) in the first ring permits water flow into an inner cavity. The second ring is movable in/out of the cavity and actuates the bracket via a locating assembly 56, compression plate 565 and T-bar 566. The second housing has a chamber defined by a diaphragm 57 operable to actuate the bracket via ejector pins 572. The bracket is hinged and rotates under the influence of the pins and T-bar to contact micro-switches (591, figure 7) that toggle the heating elements power on/off.</p> |
