*** Although Sanwa button has a good response speed from the button press, it can easily get pressed accidentally. Since the stroke of the Sanwa button is longer until the button plunger touches the bottom of the rim after the pushbutton switch is activated is longer than Seimitsu or Samducksa buttons, there are cases where it may remain turned on unless it is depressed correctly.
