#define PIN_switch_1 8   // pin number you have "snapped to"

in Setup :  pinMode (PIN_switch_1, OUTPUT);

in loop() :  digitalWrite(PIN_switch_1, (RemoteXY.switch_1==0)?LOW:HIGH);

... which makes it a "permanent" snap. There may be times when you don't want the switch to control the pin, so I prefer to create my own control code.

In your sketch you can then write something like...

if (RemoteXY.switch_1) {
  your code here
}

There's no need for any == in the comparison statement, because switch = 1 evaluates as "true"

or you can use the Switch-Case construct like

Switch (RemoteXY.switch_1) {
  case 0:
    your code here for switch off
  break;
  case 1:
    your code here for switch on
  break;
}
