I wrote the code like that,

from machine import Timer

class TOUCH(object):
    def __init__(self,pin):
        self.pin = pin
        self.tim = Timer(4)
        self.tim.init(mode=Timer.PERIODIC, period=2000,callback=self.touch_cb)
    def touch_cb(self, tim):
        print(self.pin)
    def stop(self):
        self.tim.deinit()

a = TOUCH("1")
print(a)
dir(a)
b = TOUCH("2")
print(b)
dir(b)

while 1:
    pass

I need to check that more than one button's status immediately.
and send the status via websocket.

You cannot use the same timer twice like that.

Writing machine.Timer(4) will always return back the same timer instance.

Either you should use a different timer instance for each timer, or find a way to make them use the same timer (i.e. if they're being checked at the same time, why do you need two timers?).
