Abstract
A power antenna control circuit used in a vehicle wherein a relay coil is connected to a battery through a transistor and a limit switch at the antenna lowering side and a circuit for rotating a motor by a relay switch. The transistor is turned off when an ignition switch is turned on and turned on when the ignition switch is turned off. While the ignition switch is on, the relay coil is not excited, thus enabling to reduce the electricity consumption of the battery. When the ignition is turned on, the relay coil is excited to form a circuit for rotating the motor in a direction of lowering the antenna, and, when the lowering of the antenna is completed, supply of the current to the motor and the relay coil is interrupted through the agency of the limit switch at the antenna lowering side.
