It's just a switch, not a resistor.  So the correct reading should be
normally open (infinity), and closed (close to zero ohms) when at idle
position.  Your reading of 0.4 ohms is pretty close to zero (contact
resistance and meter calibration comes into play here).  Thus, your
switch is fine.  Just make sure it's aligned correctly so that it
is indeed closed at idle and open as soon as you press down on the
