Claims

[Scope of utility model registration request]

A control circuit for an electric retractable mirror in which a mirror housing rotatably attached to a mirror base has a built-in motor and gear mechanism for tilting the mirror housing from a set position to a storage position, the control circuit comprising: a battery for applying power to the motor; A changeover switch that switches the polarity of the power supply and controls forward/reverse rotation of the motor, and is excited when current is supplied by operating the changeover switch, forming a closed current supply circuit for the motor, as well as the mirror set position and mirror storage position. A first relay circuit for applying dynamic braking to the motor, and a closed circuit for energizing the mirror housing to rotate the motor in reverse when the mirror housing is removed from the set position or storage position. A second relay circuit, a first notch that cuts off the energizing circuit of the motor at the mirror set position, and a position approximately 90 degrees offset from the first notch that cuts off the energizing circuit of the motor at the mirror set position. a second notch formed;
an approximately 172 circular conductive pattern forming an insulated line that maintains a non-conductive state during operation from the mirror storage position to the mirror set position; The relay circuit is characterized by being composed of a brush for forming a current closed circuit for the motor, the brush, a changeover switch, and a reverse current blocking diode inserted between the brush and the second relay circuit. Control circuit for electric retractable mirror.
