This article is based on information that was clearly explained in this link:

https://www.instructables.com/Two-Button-Relay-Switch/

I modified the circuit to replace the R2 resistor with a diode to improve the performance and reliability of the circuit in the link above.

Step 1: Design the Circuit

I used the PSpice student edition software version 9.1:

The light bulb can be replaced with a moderate current LED lighting source.

Step 2: Simulations

Transient (relay input voltage):

Transient (load voltage):

Conclusion

My circuit was not tested. However, I believe it can work.
