干簧管全称干式舌簧管,是一种有触点的磁控开关元件,具有结构简单、体积小、防尘、防腐、便于控制等优点,因而获得了广泛的应用。干簧管按其体积大小可分为微型、小型、大型几种;按其触点功能可分为常开触点型、常闭触点型和转换触点型几种。下面谈谈如何正确合理选用干簧管。1.首先根据电路控制要求,选择干簧管的 Reed switch full name of the dry reed switch, is a contact with the magnetic switch components, with a simple structure, small size, dust-proof, anti-corrosion, easy to control, etc., which has been widely used. Reed switch according to the size of its size can be divided into miniature, small, large several; according to their contact function can be divided into normally open contact type, normally closed contact type and conversion contact type. Here to talk about how to choose the right reed switch. First of all, according to the circuit control requirements, select the reed switch
