SRD-05VDC-SL-C datasheet

Description :

A relay that uses 5V, which is widely used in Arduino. It is a relay for 5V signal control that can be applied and used in areas requiring various contact control. It can receive a 5V signal and control the power supply up to 250V (10A). It is a compact, sealed 5-pin type, and can control NO and NC types. ( Operating voltage: 5V / Coil power consumption: 0.36 W )

2 for the coil. Middle one is COM (common) and the rest of the two are called NO (Normally Open) and NC (Normally Close). When current flows through the coil of the relay, a magnetic field is created that causes a ferrous armature to move, either making or breaking an electrical connection.
