You seem to be continuing an unrelated discussion.

Why is what happening? You have to describe your problem before asking for solutions.

Anyway - if you have a relay: do you have a freewheel diode connected in reverse over the relay coil, to take care of the energy from the coil when you deactivate the relay?

Try to drive a relay from a normal 9V battery. Disconnect the battery and look at the nice spark you get. That spark has very high voltage. Keep your fingers there and you will notice, and never forget. Besides emitting radio-wave energy (remember that the first radio transmissions was based on sparks), this spark is hurtful for a switch that is disconnecting the relay coil. And it is often fatal if the relay is driven by a transistor. With a freewheel diode, there will not be any high voltage, since the continuing current will have somewhere to go.
