    • A control unit for an electrically retractable door mirror includes a motor to drive rotationally a door mirror to a stored position or a normal position, a change-over switch, and first and second control circuits. The first and second control circuits include electronic switches respectively that are capable of switching on/off depending on the polarity of an electrical signal switched by the change-over switch. Excess current detecting devices, whose electrical resistances grow with an increase in a current, are connected to the electronic switches in series respectively. And, shutoff switches switch off the electronic switches respectively when a voltage generated in the excess current detecting devices exceeds a predetermined value.
    • 用于电气可伸缩门镜的控制单元包括电动机,用于将门镜旋转地驱动到存储位置或正常位置,转换开关以及第一和第二控制电路。 第一控制电路和第二控制电路分别包括能够根据由转换开关切换的电信号的极性来接通/断开的电子开关。 电流随着电流增加而增大的过电流检测装置分别连接到电子开关。 并且,当过电流检测装置中产生的电压超过预定值时,截止开关分别关断电子开关。
