Instructions:

1. Installation:

   • Ensure the relay is mounted on a suitable PCB with appropriate clearance.
   • Solder the relay to the PCB using a low-temperature soldering iron to avoid damaging the component.

2. Power Supply:

   • Connect the coil terminals to a 5V DC power source.
   • Ensure the power supply can provide at least 40 mA of current to operate the relay reliably.

3. Contact Usage:

   • The relay has a single pole double throw (SPDT) configuration.
   • Use the common (COM) terminal to connect the load.
   • Connect the normally open (NO) terminal to the circuit when the relay is energized.
   • Connect the normally closed (NC) terminal to the circuit when the relay is de-energized.

4. Handling:

   • Handle the relay with care to avoid mechanical stress.
   • Avoid exposing the relay to environments with high humidity or corrosive gases.

5. Testing:

   • Test the relay by applying the specified coil voltage and verifying that the contacts switch as expected.
   • Use a multimeter to check the continuity between the COM and NO/NC terminals when the relay is energized and de-energized.

6. Maintenance:

   • Regularly inspect the relay for signs of wear or damage.
   • Replace the relay if it fails to operate correctly or shows any physical damage.

7. Safety:

   • Do not exceed the maximum ratings specified for the relay.
   • Ensure proper grounding and isolation to prevent electrical hazards.
