1. A windshield heated liquid spray assembly comprising:
- a liquid heating assembly; and
a heated liquid spray assembly operative to spray heated liquid onto a windshield,said liquid heating assembly comprising;
a liquid heating chamber;
an electrical contact;
at least one heating element disposed in said liquid heating chamber; and
an electrical power supply connection that is disposed between said at least one heating element and the electrical contact, said electrical power supply connection including;
an electrically-conductive housing that is electrically and thermally coupled to the liquid heating chamber,an electrically-insulative element that is disposed between the electrical contact and the electrically-conductive housing, anda meltable conductor portion that is electrically and thermally coupled to said electrical contact and to said electrically-conductive housing and being operative to melt, and thus to interrupt supply of electrical power to said at least one heating element, in response to heating of said liquid heating chamber above a predetermined temperature.
