Blind electrical connection through spring contacts in motor control center

A system for controlling a motor for industrial applications includes a motor control center and a motor control unit. The motor control center has at least one printed circuit board and a motor control unit having at least one pin. At least one pin includes a barrel, a plunger, and a spring. The motor control unit is selectively insertable into the motor control center, while the at least one pin transitions from a first position to a second position when inserted, and the at least one pin is connected to the at least one printed circuit board to form an electrical connection between the motor control center and the motor control unit. 一种用于对工业应用所用的马达进行控制的系统，该系统包括马达控制中心和马达控制单元。马达控制中心具有至少一个印刷电路板和具有至少一个引脚的马达控制单元。至少一个引脚包括筒、柱塞和弹簧。马达控制单元能够选择性地插入到马达控制中心中，而至少一个引脚在插入时从第一位置过渡至第二位置，并且至少一个引脚连接至至少一个印刷电路板从而在马达控制中心与马达控制单元之间形成电连接。
