Say I have 4 switches controlling 2 servos, can I use this block

if SW1==1 && SW2==0 && SW3=0 && SW4==0  
{servo1.write(30);servo2.write(60);}  
else if SW1==1 && SW2==1 && SW3=0 && SW4==0  
{servo1.write(60);servo2.write(90);}  
else if SW1==1 && SW2==1 && SW3=1 && SW4==0  
{servo1.write(90);servo2.write(120);}  
else if SW1==1 && SW2==1 && SW3=1 && SW4==1  
{servo1.write(120);servo2.write(150);}

if the answer is yes, how many layers of if-else one can use? is there a limit ?
