Stuck with simple motor circuit

i trying build simple circuit in dc motor controlled spdt slide switch.  programme seems fine , can run - trouble is, can't switch control motor switching on , off.  clues? i'm doing stupid!  thanks.

int switcha = 7;
int motora = 2;

void setup(){
  pinmode(switcha,input);
  pinmode(motora,output);
}

void loop(){
  if(switcha,high){
    digitalwrite(motora,high);
    delay (1000);
    digitalwrite(motora,low);
    delay(2000);
  }
  else{
    digitalwrite(motora,low);
  }
}

hopefully link takes 123d simulation circuit.

don't connect motor directly arduino pin.
that damage pin and/or arduino.
pins rated 20ma (40ma absolute max).

motors should switched suitable resistor/transitor circuit emf diode.

it seems have connected 9volt battery arduino's 5volt pin.
that smoke arduino.

connect switch input pin , ground. no resistor.
enable internal pullup resistor in pinmode.
