os.system is not patched, but subprocess.call is patched; Replace os.system with subprocess.call (You can also use subprocess.run if you are using Python 3.5+)

import subprocess

...

def print_head(i):
    switch = '192.168.182.170'
    response = subprocess.call("ping " + switch, shell=True)

The problem is that os.system("ping -c 5 " + switch) is running synchronously, because the function is blocking. You should try to do it in different processes.

Here is a concurrent code that does the same.

from multiprocessing import Process
import os

def print_head(i):
    switch='192.168.182.170'
    response = os.system("ping -c 5 " + switch)

processes = [Process(target=print_head, args=(i,)) for i in range(1,10)]
for process in processes:
    process.start()
