Much thanks your great ideal.
I surveyed some two position switches which can be located on bottom 
side of board or on left or right side of board. :-)    Using a two 
position switch may better than a push button.

No, my ideal was totally not good. so we'll have a real like slide 
switch[1] for bottom of board or slide switch[2] for side of board. But 
I have to check if having bottom or side of device from layout space 
check. And check with vendor which one is the most popular and easier get.
Will keep list posted.
