Please suggest device that convert signal from push button 220v to 0/1-10v output. Thanks

It depends on what you intend to do with that 10-volt output. How much current is needed? I assume you want +10 volts DC when the button is pushed.

If you don't need much current and if you are not concerned with safety, you could use a resistive voltage divider followed by a half-wave rectifier and capacitive filter to get the +10 volts.

If you need more current or you are concerned about safety then get an isolation transformer with a 220-volt primary and a 10-volt secondary and make a little power supply.
