Appearance structure: The relay has a white plastic shell with a black plastic cover on it, under which are the contacts and coils of the relay.
Contacts: There are multiple metal contacts inside the relay, which are used to connect the circuit. The contacts are usually made of copper or other conductive metals to ensure a good electrical connection.
Pins: There are metal pins at the bottom of the relay, which are used to connect the power supply and control circuit. The design of the pins allows the relay to switch the on and off state of the circuit when it receives a signal.

Rated voltage: The relay is marked with "220V", which may indicate that its rated voltage is 220 volts and is suitable for 220V circuit systems.
Model identification: The relay is marked with "103N 06", which may be part of its model or specification to identify the specific characteristics of the relay.
Application: This type of relay may be used in various electronic devices, such as household appliances, industrial control, automotive electronic systems, etc., to control the flow of current and achieve automatic control.
Color: The shell color of the relay is white and black, which may be to distinguish different models or applications.
