作为控制转向指示灯闪烁的闪光继电器,旧式车多采用双金属丝式的,即通过电阻丝红热膨胀,与电磁式继电器的线圈配合,调节触点的不断开闭,造成指示灯的亮或灭。日本日产各型车装用的晶体管闪光继电器,系利用了晶体三极管本身具有的开关特性作为继电器的控制开关,实际上形成了一个晶体管延时开关电路。它是根据电流从高电位流入 As a control blinking flash relay light relay, the old car to use more bimetal wire, that is, through the thermal resistance of red hot expansion, with the electromagnetic relay coil, adjust the contact opening and closing, causing the light on or off . Japan Nissan all kinds of vehicles equipped with transistor flash relay, the use of the transistor transistor itself has the switching characteristics of the relay control switch, in fact, formed a transistor delay switch circuit. It is based on the current flowing from a high potential
