ABSTRACT:
A trigger switch includes a first locating element, an elastic second locating element, and a pressing element slidably attached to the bezel. The pressing element is restricted by the first locating element to a first position of the bezel to prevent the trigger portion from contacting the trigger element. The second locating element restricts the pressing element to a second position of the bezel to further prevent the trigger portion from contacting the trigger element. The trigger portion contacts and applies a force to the trigger element to trigger the trigger element when the pressing element overcomes elastic forces of the second locating element.
