• an obstruction member movable between a first position and a second position, wherein the button is depressible from an undepressed position to a depressed position to engage the activation element of the switch when the obstruction member is in the first position, wherein the button is blocked from being depressible to the depressed position when the obstruction member is in the second position, wherein the obstruction member is between the switch and the button when in the second position;
• a selector operable to cause the obstruction member to move between the first position and the second position;
• and
• a motion changing arrangement operatively arranged between the selector and the obstruction member to transform a motion of the selector into a motion of the obstruction member for moving the obstruction member between the first position and the second position.
