A toilet seat has a heater connected to a controller for supplying heating current thereto via a first cable. A thermo-sensor in the toilet seat provides temperature signals to the controller via a second cable. The controller terminates the current to the heater upon the termination of signals from the thermo-sensor. The wires of the second cable have a diameter larger than those of the first cable, so that the wires of the second cable, which provide the temperature signal to the controller, will fail due to bending stresses upon repeated raising and lowering of the toilet seat, before the wires of the first cable. This will cause the controller to terminate the supply of current to the heater.
