Smart Switch

Hello everyone!
I need to make a smart switch so I am seaching some options.
The project is: with a remote control via IR the arduino will capture the signal and open or close the circuit between the eletrical grid(220v) and a power supply (like this -> Buy 10w 400w All series parameter can in China on Alibaba.com)(will be between 50-600w).
I seach and I found this -> Arduino-controlled-plug-to-plug-switch, but after that I read that I shoud use an solid state relay instead a normal relay, because the user maybe would open and close the circuit a lot of times.
What shoud I do?

Thank you for your time!

Use a relay. That Instructable seems better than most others.

That kind of power supply will have a very high inrush current when it’s switched on. Make sure whatever relay you buy has a lot more amps than the power supply does.

How I know the inrust corrent?
After all that will not be a powersuplly, will be a transformer because will be ac to ac

Assume it is five to ten times the rated current.

What you cited is a switchmode power supply with a high inrush current. Better ones have a NTC thermistor to limit this, but they tend to have a significant failure rate.

Why should I get a NTC thermistor?

Unless you are a power supply engineer, then no.
