Hi,
When i am switching relay on and off i am seeing some fluctuations in my DC supply, I am using freewheeling diode also. I am not able to solve this problem. Please advice some solution for this problem.

if the supply provides power to to the switched contacts of the relay ← (then) it's trivial

if the supply does not provide power to to the switched contacts of the relay ← it's the relay coil being connected(/powered) and disconnected(/un-powered)
