To the frost protection device for automobile glass that controls the power supplied to the heated glass by using a poly switch in response to the heated timer for controlling the power supplied to operate the heated glass for removing frost generated on the glass of the vehicle. The present invention relates to a heated glass which generates heat from an internal heating wire by a supplied power supply and removes frost generated in the glass. When the switching contact is turned on by a user's contact selection, the contact glass is maintained to maintain the contact on state. Supply means for supplying power to the switching means that the contact is turned off when the supply power of the heated glass is cut off, and to cut off the supply power according to the temperature by the amount of current supplied to the heated glass when the contact of the switching means is turned on It further comprises a power supply control means to respond to expensive timer device By using a cheap poly switch, it is possible to reduce the cost and reduce the burden on the user by using a relay contact switch for a push contact switch that is turned on and off by the user.
