Advantages:

 

  • Easy Installation: Spade terminals can be quickly connected and disconnected, suitable for situations requiring frequent replacement or maintenance.
  • High Reliability: When properly installed, the connection is very secure and not easily loosened.
  • Wide Applicability: Suitable for connecting various types of wires and equipment.

 

Disadvantages:

 

  • Requires Tools: Installation and removal usually require the use of tools such as screwdrivers.
  • Limited Contact Area: Compared to screw terminals, the contact area is smaller, which may affect current transmission efficiency.
  • Vibration Sensitivity: In high-vibration environments, the connection may become loose.
