Electrical Switch

Product Details:

It looks like you are asking about DC sockets. A DC socket (also known as a DC power jack or DC connector) is an electrical connector used to supply direct current (DC) power to electronic devices.

• Function: It allows a device to receive power from an external power supply (like an adapter or battery pack).
• Design: Usually consists of a cylindrical female socket that connects to a male DC plug.
• Voltage & Current Ratings: Available in different voltage and current ratings (e.g., 5V, 12V, 24V, etc.).
• Pin Configuration: Typically, DC sockets have:
  • Outer barrel (sleeve) – often negative (-).
  • Inner pin (center pin) – often positive (+).
• Mounting Types:
  • Panel mount – fixed to a panel or casing.
  • PCB mount – soldered directly onto a circuit board.
• Common Sizes: The most common DC socket sizes are 5.5mm outer diameter / 2.1mm inner diameter and 5.5mm outer / 2.5mm inner.
