However, this design has many shortcomings: first, the pins of the indicator lights are usually hard pin structures. When the indicator lights are directly mounted on the chassis, they need to be welded to the indicator light pins by wires and then connected to the circuit board. Since the wires and pins are thin, the welding points are easy to break when the controller is subjected to vibration or impact, causing the indicator lights to fail, thereby affecting the reliability of the controller; secondly, for controllers that require multiple indicator lights, multiple indicator light installation holes need to be opened on the chassis, which will greatly affect the anti-interference and waterproof capabilities of the controller, especially for special controllers with electromagnetic shielding and waterproof requirements. This design is difficult to meet their performance requirements; in addition, the process of installing indicator lights one by one is also quite cumbersome, which increases the difficulty of the production line operation and is not conducive to improving production efficiency.
