Claims

[Scope of utility model registration request]

A power supply circuit that supplies the power supplied through the ignition switch to the defogger hot wire has a relay contact, and the power supply circuit opens and closes in accordance with the operation of the ignition switch or relay to supply power to the defogger hot wire. In a hot wire defogger device for a vehicle that controls supply, a first switch consisting of a normally open contact that closes only when operated;
A second switch consisting of a normally closed contact whose contacts open only when operated; When closed, the relay coil is energized to maintain the power supply circuit in a closed state, and when a contact of a second switch is opened, energization to the relay coil is cut off to open the power supply circuit. Features: Hot-wire defogger device for vehicles.
