What type of relay is it?
Electromagnetic intermediate mini relay, 2NO + 2NC (DPDT – double pole double throw), having two normally open (NO) and two normally closed (NC) contacts.

Where is this relay used?
Widely used for circuit control: in automation panels, PLC control systems, signal switching, control of contactors, DIY and Smart Home projects, lighting control, temperature and humidity control systems, as well as for controlling multiple higher-power loads simultaneously using low-current signals.

What is the main function of the relay?
Allows low control voltage to control higher loads and simultaneously switch multiple independent circuits, separating control and power circuits.

How is it installed?
Into a PCB board, into a socket / holder, using contact pins.
