Solenoid actuator to push a button

You want a diode across relay to limit switch arcing :



If your relay coil is rated for 12 V no need for series R. Also
why do you have a series diode ? Not sure why thats needed.

Do you want, after release of button, relay to stay on ? Latch ?
Eg. one push relay stays on, next push relay stays off. If so use a
latching relay.

Having a resistor and LED in series with the relay coil severely limits the number of relays you have to choose from. The odds of the relay coil going open circuit are extremely low. Since you already have an LED indicator showing that the circuit has been powered, I would eliminate the one in series with the coil.

And add a suppression diode as in the other answer.

Next, select the solenoid and post its characteristics (voltage / current / power). Once you have this, we can guide you in selecting the relay.

Any particular reason you are not driving the solenoid directly with the switch?
